CASE VIII.

Col. William Scollay, aged fifty-two, of a plethoric habit of body, was attacked, in the year 1805, with dyspnœa and palpitation of the heart, attended with irregularity of the pulse, and œdema of the lower extremities. By the aid of medicine, the dropsical collections were absorbed, and he recovered his health, so far as to follow his usual occupations, nearly a year; but was then compelled to relinquish them. The symptoms afterwards underwent various aggravations and remissions, till the beginning of the winter of 1808-9, when the attacks became so violent, as to confine him to the house. His face was then high coloured. The faculties of his mind were much impaired. The dyspnœa became more constant, and was occasionally attended by cough; the palpitations rather lessened in violence; the pulse was more irregular, and exceedingly intermittent. The abdomen and inferior extremities were sometimes enormously distended with water, and afterwards subsided nearly to their usual size. One of the earliest, most frequent, and distressing symptoms, was an intense pain in the head. About two months before death, a hemiplegia took place, but after a few days disappeared. This so much impaired the operations of the mind, that the patient afterwards found great difficulty in recollecting words sufficient to form an intelligible sentence. During the existence of the last symptom the pulse was regular.

He gradually expired, on the 15th of March, 1809.

DISSECTION, FIVE HOURS AFTER DEATH.

EXTERNAL APPEARANCE.

The countenance was somewhat livid and pale; the lips were very livid. The chest resounded, when struck, except over the heart. The abdomen was tumid, and marked by cicatrices like those of women, who have borne children. The superior extremities were emaciated, and marked like the abdomen. The lower extremities were œdematous.

THORAX.

The cartilages of the ribs were ossified. The left cavity of the pleura contained about twelve ounces of water; the right, about three ounces. The lungs, externally, were dark coloured, especially the posterior lobes; internally, they were very firm, and, in some places, as dense as the substance of the liver. A frothy mucus was effused from them in great quantities. They were coloured by very dark blood, especially in the middle portion of the left superior lobe. One or two calcareous concretions were observed in them. The pericardium was a little firmer than usual, and contained about five ounces of water. The heart was enlarged, and covered with tough fat. In the right auricle, and ventricle, was some coagulated blood. The tricuspid valves had lost their smoothness and transparency; the semilunar valves of the pulmonary artery were cartilaginous at their bases. The left auricle and ventricle, particularly the first, contained coagulum. The mitral valves were roughened by many bony spots. Considerable ossification had taken place in the semilunar valves of the aorta, so that one of them had quite lost its form; and the aorta was ossified for the space of a square inch, at a small distance from the valves. The coronary arteries were also ossified.

ABDOMEN.

The coat of the liver was somewhat wrinkled, as if shrunk. Its substance was hard, and discharged, when cut, great quantities of blood. The veins of the omentum, mesentery, and intestines, were full of blood. The abdomen contained a considerable quantity of water.

HEAD.

Water was found between the dura and pia mater, and between the pia mater and arachnoides. The vertical portion of the pia mater bore marks of former inflammation. The convolutions of the brain were very distinct; their external surface was pale. The veins were empty[11]. No bloody points were observed in the medullary portion of the brain, when cut. The ventricles contained between one and two ounces of water; the communication between them was very large. The plexus choroides was pale.

CASE IX.

A lady, about forty-five years of age, the mother of many children, has been troubled during the course of the past year with violent palpitations of the heart, and great difficulty of respiration, especially on going up stairs. These complaints have lately increased, so that she has kept in her chamber about two months. Her countenance is florid; her eyes are clear and bright. She has dizziness, especially on moving, without pain in her head. She had for some time, a severe cough, which is now relieved. The dyspnœa is not yet very distressing, except on using motion; it often occurs in the night, and obliges her to rise and sit up in bed. The palpitations are very hard, and so strong, that they may be perceived through her clothes; the tumult in the thorax is indescribable. The functions of the abdominal viscera are unimpaired. The pulse is hard, vibrating, irregular, intermittent, very variable, corresponding with the motions of the heart, and similar in each arm. There is not yet the slightest reason to suspect any dropsical collection. The alternations of ease and distress are very remarkable, but on the whole, the violence of the symptoms increases rapidly.

There is no difficulty in discovering in this case an organic disease of the heart, which probably consists in an enlargement and thickening of the heart, and an ossification of the semilunar valves of the aorta.

CASE X.

Levi Brown, a cabinet-maker, forty-eight years of age, complained in February, 1809, of great difficulty of breathing, and an indescribable sensation in the chest, which he said was sometimes very distressing, and at other times quitted him entirely. Being a man of an active mind, he had read some medical books, whence he got an idea, that he was hypochondriac.

On examining his pulse, it was found to be occasionally intermittent, contracted, and vibrating. He had some years previously been attacked with copious hæmorrhages from the stomach or lungs, which have occasionally recurred, though they have lately been less frequent. Eight years since he suffered from an inflammation of the lungs; and about two or three years ago he first experienced a beating in the chest, and pain in the region of the heart, which increased till within six or eight months, since which the beating has been stationary, and the pain has much increased. In the course of the last summer, dyspnœa, on using exercise, and especially ascending any eminence, commenced. This has greatly increased, so as to render it almost impossible for him to go up stairs. His countenance is turgid, and uniformly suffused with blood; his eyes are bright and animated; his lips livid. The pulsation of the heart cannot be felt on the left side, and is barely perceptible on the right side of the sternum, and in the epigastric region. When he is distressed with fits of dyspnœa, he feels something as if rising to the upper part of the thorax, and the heart then seems to him to be beating through the ribs. I have not witnessed any of these paroxysms. The inferior extremities and abdomen have been swelled about three weeks. When in bed, he has his head and shoulders elevated, and, upon the attack of his paroxysms, sits up and inclines his head forward; but he keeps from the bed as much as possible. In his sleep he is apt to start up, suddenly, in distress, especially when he first slumbers. His dreams are often frightful, and, when awake, he is affected with reveries, during which, though conscious of being awake, strange illusions present themselves. At intervals he seems slightly delirious. He has a violent cough, with very copious expectoration of thick mucus. He often suffers from severe head-ache, and the least exercise produces dizziness.

This man has a very robust frame of body, and has been accustomed to a free use of ardent spirits, and of opium, of which he now takes about twelve grains in a day. His appearance is such, that, on a slight survey, one would not suppose him diseased, but, on observing him with a little attention, a shortness and labour of respiration are perceived, with some interruption in speaking, and a frequent catching of the breath, or sighing.

April. Since writing the above account, the dropsical collections were absorbed, and the palpitations and other symptoms moderated, so that he considered himself nearly well, and attended to his usual business. Within a few days, however, the symptoms have returned with more violence. The dyspnœa is at times very distressing; the pulse more irregular and intermittent; the palpitations are more constant. His sufferings from lying in bed are so increased, that in the most comfortable nights he passes, he sits up once in an hour or two. The appetite is keen. The legs begin to swell again.

Some organic disease of the heart exists in this case. The indistinctness of the palpitations, the want of hardness in the pulse, and the slow progress of the disease, indicate a loss of power in the heart, the effect of the distention and thinness of its parietes. The irregularity of the pulse affords some reason to suspect disorder of the aortal valves, which is not yet very considerable.

REMARKS.

The symptoms, which are most observable, in some or all of the preceding cases, are the following:

The first notice of disorder is commonly from an irregular and tumultuous movement of the heart, which occurs some time before any perceptible derangement of the other functions. This irregularity slowly increases, and arrives at its height before the strength of the patient is much impaired, at least in the cases which I have noticed; and as the vigour of the patient lessens, the force of the palpitations diminishes. These palpitations are often so strong, as to be perceptible to the eye at a considerable distance. They are seldom most distinct in the place where the pulsation of the heart is usually felt. Sometimes they are perceived a little below; often in the epigastric region; and not unfrequently beneath, and on the right side, of the sternum.

After the palpitations have lasted some time, a little difficulty of breathing, accompanied with sighing, is perceived, especially on any great exertion, ascending an eminence, or taking cold, of which there is an uncommon susceptibility. This dyspnœa becomes, as it increases, a most distressing symptom. It is induced by the slightest cause; as by an irregularity in diet, emotions of the mind, and especially movement of the body; so that on ascending stairs quickly, the patient is threatened with immediate suffocation. It occurs at no stated periods, but is never long absent, nor abates much in violence during the course of the disease. It is attended with a sensation of universal distress, which perhaps may arise from the circulation of unoxygenated blood, or the accumulation of carbon in the system; for the countenance becomes livid, and the skin, especially that of the extremities, receives a permanent dark colour. This dyspnœa soon causes distress in lying in an horizontal posture. The patient raises his head in bed, gradually adding one pillow after another, till he can rarely, in some cases never, lie down without danger of suffocation; he inclines his head and breast forward, and supports himself upon an attendant, or a bench placed before him. A few hours before death the muscular power is no longer capable of maintaining him in that posture, and he sinks backward. The dyspnœa is attended with cough, sometimes through the whole of the disease, sometimes only at intervals. The cough varies in frequency. It is always strong, and commonly attended with copious expectoration of thick mucus, which, as the disease advances, becomes brown coloured, and often tinged with blood; a short time before death it frequently consists entirely of black blood.

The changes in the phœnomena of the circulation are very remarkable. The sanguiferous system is increased in capacity; the veins, especially, are swelled with blood; the countenance is high coloured, except in fits of dyspnœa, when it becomes livid; and it is very frequently puffed, or turgid. The brightness of the eyes, dizziness, which is a common, and head-ache, which is a frequent symptom, and in some cases very distressing, are probably connected with these changes. The motions of the heart, as has already been stated, are inordinate, irregular, and tumultuous. The pulse presents many peculiarities. In some cases, probably where there is no obstruction in the orifices of the heart, it remains tolerably regular, and is either hard, full, quick, vibrating and variable, or soft, slow, compressible and variable. Most commonly, perhaps always, when the orifices of the heart are obstructed, it is vibrating, very irregular, very intermittent, sometimes contracted and almost imperceptible, very variable, often disagreeing with the pulsations of the heart, and sometimes differing in one of the wrists from the other.

The functions of the brain suffer much disturbance. Melancholy, and a disposition for reverie, attend the early stages of the complaint; and there is sometimes an uncommon irritability of mind. The dreams become frightful, and are interrupted by sudden starting up in terror. Strange illusions present themselves. The mental faculties are impaired. The termination of the disease is attended with slight delirium; sometimes with phrenzy, and with hemiplegia.

The abdominal viscera are locally, as well as generally, affected. Although the digestive functions are occasionally deranged, the appetite is at some periods remarkably keen. The action of the intestines is sometimes regular, but a state of costiveness is common. The liver is often enlarged, probably from accumulation of blood. This distention is attended with pain, varies much, and, in all the cases I have seen, has subsided before death, leaving the coats of the liver wrinkled, flaccid, and marked with appearances of inflammation, caused by the distention and pressure against the surrounding parts. An effect of the accumulation of blood in the liver, and consequently in the mesenteric veins, is the frequent discharge of blood from the hæmorrhoidal vessels. This occurs both in the early and late stages of the disease, and may become a formidable symptom. Evacuations of blood from the nose are not uncommon.

Dropsical swellings in various parts of the body succeed the symptoms already enumerated. They commence in the cellular membrane of the feet, and gradually extend up the legs and thighs; thence to the abdominal cavity, to the thorax, sometimes to the pericardium, to the face and superior extremities; and, lastly, to the ventricles and meninges of the brain. These collections of water may be reabsorbed by the aid of medicine; but they always return and attend, in some degree, the patient’s death.

There is no circumstance more remarkable in the course of this complaint, than the alternations of ease and distress. At one time the patient suffers the severest agonies, assumes the most ghastly appearance, and is apparently on the verge of death; in a day or a week after, his pain leaves him, his appetite and cheerfulness return, a degree of vigour is restored, and his friends forget that he has been ill. The paroxysms occasionally recur, and become more frequent, as the disease progresses. Afterwards the intermissions are shorter, and a close succession of paroxysms begins. If the progress of the complaint has been slow, and regular, the patient sinks into a state of torpor, and dies without suffering great distress. If, on the contrary, its progress has been rapid, the dyspnœa becomes excessive; the pain and stricture about the præcordia are insupportable; a furious delirium sometimes succeeds; and the patient expires in terrible agony.

Such are the symptoms, which a limited experience has enabled me to witness. Others, equally characteristic of the disease, may probably exist.

From this description of the symptoms it would appear, that there could be no great difficulty in distinguishing this from other diseases; yet probably it has sometimes been confounded with asthma, and very frequently with hydrothorax. Some may think, that there is no essential difference in the symptoms of these diseases. The resemblance between them, however, is merely nominal.

The cough in hydrothorax, unlike that which attends organic diseases of the heart, is short and dry; the dyspnœa constant, and not subject to violent aggravations. An uneasiness in a horizontal posture attends it, but no disposition to incurvate the body forward. These are some of the points, in which these two diseases slightly resemble each other. Those, in which they totally differ, are still more numerous; but as most of them have been already mentioned, it is unnecessary to indicate them here.

It is probable, that the two diseases commonly arise in patients of opposite physical constitutions; the hydrothorax in subjects of a weak relaxed fibre; the organic diseases of the heart in a rigid and robust habit. The subjects of the latter affection, in the cases which have fallen under my observation, were, with the exception of one or two instances, persons of ample frame, and vigorous muscularity, and who had previously enjoyed good health. In nearly all these cases the collection of water was principally on one side, yet the patients could lie as easily on the side where there was least fluid, as on the other; which, in the opinion of most authors, is not the case in primary hydrothorax. It should also be observed, that, in many of the cases, there was only a small quantity of water in the chest, and that in neither of them was there probably sufficient to produce death. May not primary hydrothorax be much less frequent, than has commonly been imagined?

Idiopathic dropsy of the pericardium may, perhaps, produce some symptoms similar to those of organic disease of the heart; but it appears to be an uncommon disorder, and I have had no opportunity of observing it. In the [fourth case], a remarkable disposition to syncope, on movement, distinguished the latter periods of the disease, and might have arisen from the great collection of water in the pericardial sac.

The causes of this disease may, probably, be whatever violently increases the actions of the heart. Such causes are very numerous; and it is therefore not surprising, that organic diseases of the heart should be quite frequent. Violent and long continued exercise, great anxiety and agitation of mind[14], excessive debauch, and the habitual use of highly stimulating liquors, are among them.

The treatment of this complaint is a proper object for investigation. Some of its species, it is to be feared, must forever remain beyond the reach of art; for it is difficult to conceive of any natural agent sufficiently powerful to produce absorption of the thickened parietes of the heart, and at the same time diminish its cavities; but we may indulge better hopes of the possibility of absorbing the osseous matter and fleshy substance deposited in the valves of the heart and coats of the aorta. A careful attention to the symptoms will enable us to distinguish the disease, in its early stages, in which we may undoubtedly combat it with frequent success.

Although it may not admit of cure, the painful symptoms attending it may be very much palliated; and, as they are so severely distressing, we ought to resort to every probable means of alleviating them. Remedies, which lessen the action of the heart, seem to be most commonly indicated. Blood-letting affords more speedy and compleat relief, than any other remedy. Its effect is quite temporary, but there can be no objection to repeating it. The digitalis purpurea seems to be a medicine well adapted to the alleviation of the symptoms, not only by diminishing the impetus of the heart, but by lessening the quantity of circulating fluids. Its use is important in removing the dropsical collections; and for this purpose it may often be conjoined with quicksilver. Expectoration is probably promoted by the scilla maritima, which, in a few cases, seemed also to alleviate the cough and dyspnœa. Blisters often diminish the severe pain in the region of the heart, and the uneasiness about the liver. It has been seen, that the excessive action of the heart sometimes produces inflammation of the pleura and pericardium, and that the distention of the coat of the liver has the same effect upon that membrane in a slighter degree. Vesication may probably lessen those inflammations. When the stomach and bowels are overloaded, a singular alleviation of the symptoms may be produced by cathartics, and even when that is not the case, the frequent use of moderate purgative medicines is advantageous. Full doses of opium are, at times, necessary through the course of the complaint. The antiphlogistic regimen should be carefully observed. The food should be simple, and taken in small quantities, stimulating liquors cautiously avoided, and the repose of body and mind preserved, as much as possible.

The causes of some of the phœnomena of this disease are easily discovered; those of the others are involved in obscurity, and form a very curious subject for investigation. I shall not at present trouble you with the ideas relating to them, which have occurred to me, but hope to be able to present some additional remarks on the subject, at a future period. In the mean time, I beg leave to invite the attention of the society to the observation of the symptoms of this interesting disorder, and of the morbid appearances in the dead bodies of those, who have become its victims.

At the time the preceding pages were going to the press, the subjects of the [ninth] and [tenth] cases died, on the same day, and an opportunity was given of ascertaining whether their complaints had been rightly distinguished.

It is a proof of an enlightened age and country, that no objections were made in any instance to the examinations, which have afforded us so much useful information.

DISSECTION OF CASE NINTH.
THIRTY HOURS AFTER DEATH.

The lady, who was the subject of this case, died on the 10th of May, but she was not seen by me after the 29th of March; so that it is not in my power to relate exactly the symptoms which attended the latter stages of her complaint. I was informed, however, that they increased in violence, especially the difficulty of breathing, and inability to lie down; that her cough returned, and her expectoration was sometimes bloody; and that, for sometime before death she suffered inexpressible distress.

We found the body somewhat emaciated, and the lower extremities and left arm œdematous. Might not this swelling of the left arm have depended on her constant posture of inclining to her left side?

The face, especially at the lips, was livid, though not so much as in many other cases of this disease. On the left shoulder were small, hard, and prominent livid spots.

The cellular membrane, both on the outside and inside of the thorax, was quite bloody, which is not usually the case in dead bodies. The cartilages of the ribs were slightly ossified, and, upon their removal, it appeared that the pericardium and its contents occupied an extraordinary space, for the lungs were quite concealed by them. These organs being drawn forward, appeared sound and free from adhesions; their colour, anteriorly, was rather dark; posteriorly, still darker; their consistence firm. Their vessels were so crowded with blood, as to cause an uniform dark colour in the substance of the lungs, especially in some particular spots, where the blood appeared to be accumulated; but whether this accumulation was confined to the blood vessels, or extended to the bronchial vesicles, could not be satisfactorily determined. No one can doubt that blood may be frequently forced through the thin membrane of the air vesicles, who considers, that in these cases the heart often acts with uncommon violence, that, when it is enlarged, it attempts to send toward the lungs more blood than their vessels can contain, and that there is commonly some obstruction to the return of blood from the lungs into the heart, from derangement either in the mitral or aortal valves, or in the aorta. The consequent accumulation of blood in the lungs seems to me to be the probable cause of the dyspnœa, which so much distresses those affected with diseases of the heart; for if there be an inordinate quantity of blood, there must be a deficiency of air.

This accumulation of blood in the lungs has, by some writers, been considered as an appearance belonging to idiopathic hydrothorax. Whether it ever exists in that complaint seems to me uncertain. The pressure of water upon the lungs, may possibly interrupt the free circulation of blood through their vessels, yet probably the same pressure would prevent the entrance of blood into the vessels, unless there be some other cause to overcome it, such as increased action of the heart, which attends only the first stage of hydrothorax. It has beside been proved by the experiments of Bichat, that the collapsion of the lungs does not obstruct the circulation of blood through the pulmonary vessels. It seems probable, therefore, that those who have thought this collection of blood an appearance belonging to idiopathic hydrothorax, have mistaken for it the secondary hydrothorax produced by diseases of the heart.

On pursuing the examination, we found, behind the lungs, about five or six ounces of yellowish serum in each cavity of the pleura, and about one ounce in the cavity of the pericardium. The heart was then seen enlarged to more than double its natural size. Its surface, especially along the course of the branches of the coronary arteries, was whitened by coagulated lymph. In the cavities of the heart, which were all enlarged and thickened, particularly the left, were found portions of coagulum mixed with fluid blood. Near its apex, over the left ventricle, was a small soft spot which, to the finger, seemed like the point of an abscess ready to burst. The tricuspid valves, and the valves of the pulmonary artery, had lost somewhat of their transparency, and were a little thickened, though not materially. It is worthy of remark, that these valves have not exhibited any great appearance of disease in any of these cases, while those of the left side of the heart have scarcely ever been found healthy. So it appeared in this case. The mitral valves were uniformly thickened, and partly cartilaginous; the left portion adhered to the side of the heart. The valves of the aorta had lost their usual form, were entirely cartilaginous, and almost equal in firmness to the aorta, which was cartilaginous under the valves, sound in other parts, and rather small, compared to the size of the heart.

It may be thought that the symptoms, on which reliance was placed to distinguish disorder of the valves of the aorta, are fallacious, because it was supposed that these valves would be found ossified, when they were in reality only cartilaginous. The difference, however, would be small in the effects produced on the circulation by such a state of the valves as existed in this case, and a very considerable ossification; for, if the valves were rigid and unyielding, it is of little importance whether they were rendered so by bone, or cartilage. Whether the irregularity of the pulse in these diseases generally depends on the disorganized state of the aortal, or other valves, we have not at present observations sufficient to decide. In the [sixth case] no irregularity of the pulse could be observed, although the other symptoms were unequivocal, and no disease was found in the valves; while, on the other hand, we find that the valves in the [fourth case] were not importantly deranged, and yet there was an irregularity and intermission of the pulse, which however might be attributed to the dropsy of the pericardium. In the [seventh case], where the pulse was not irregular, the valves of the aorta were “considerably thickened in various spots;” in the fifth, the pulse was irregular, and the valves were not materially altered, but there was water in the pericardium. In all the other cases, the pulse was irregular, and the valves were much disordered: On a review of these cases, therefore, we find some reason to believe, that the irregularity of the pulse depends much on disease of the valves, especially those of the aorta.

The cavity of the abdomen being opened, no water was discovered in it, nor any other uncommon appearance, except about the liver, the coat of which had been rendered opaque by coagulated lymph, and was studded over with soft, dark coloured tubercles. The substance of the liver was tender, and full of bile and venous blood.

DISSECTION OF CASE TENTH.
TWENTY-FOUR HOURS AFTER DEATH.

The symptoms of disease in this patient did not alter much, except in degree, from the middle of April to the 10th of May. He became weaker, had more straitness and pain about the heart on moving, an increase of swelling in the legs and abdomen, return of the cough, and a pain from the left shoulder to the middle of the arm. After his relapse in April, he had been directed to employ blisters, the submuriate of quicksilver, and the tincture of the digitalis purpurea. The dose of the tincture he gradually increased, till he took two hundred drops, two or three times in a day. Notwithstanding a profuse flow of urine, the legs became so hard and painful, that I made punctures to discharge the water from them. He would have had the water in the abdomen drawn off, but believing it would not afford him great relief, I dissuaded him from it. On the 10th of May, after having passed an unusually comfortable night, he rose and left his chamber for five or six hours, then retiring to it again, said he would be tapped that day, and, after lying down, was quitted by his attendant, who went in an hour after and found him dead. This was rather unexpected, for he had the appearance of sufficient vigour to struggle with disease three or four weeks longer.

A number of medical gentlemen being assembled, as has been usual on these occasions, we first remarked, that the face was swollen, and extraordinarily livid; for, although a considerable degree of lividity, and sometimes of redness, after death, is peculiar to these cases, we had seen none which resembled this. Hard and prominent purple spots were observed upon the shoulders, side, and back. The surface of the body was moderately covered with fat; the legs and abdomen were much swollen with water, the arms more slightly. The integuments of the thorax being cut through, the cellular membrane discharged a serous fluid from every part; these being turned aside, to lay bare the cartilages of the ribs, we found them completely ossified; and having divided them, with a saw, the cavity of the thorax was opened. The cellular membrane, inside the thorax, about the mediastinum, had not so bloody an appearance as we witnessed in the preceding cases, nor were the lungs, either externally or internally, so dark coloured as usual, though they were much darker, firmer, and more filled with blood, than is common in subjects of other diseases. The lungs of the left side adhered closely to the pleura costalis, and those of the right were tied by loose and membranous adhesions; beside which there was no appearance of disease about them. The cavity of the pleura did not contain any water; that of the pericardium held about six ounces.

The anterior surface of the heart exhibited a considerable whiteness of its coat over the coronary arteries. This appearance differed from that of other cases, in being contained in the substance of the membrane, instead of lying on its surface; and, either from this circumstance, or from the length of time since it had existed, its aspect was so peculiar that it might be supposed to be the first stage of an ossification. A deposition of lymph on the heart has been observed in every one of these cases of organic disease, and it has existed principally over the branches of the coronary arteries, or else near the apex of the heart, which is to be attributed to the irritation of the membrane by the combined impulse of the heart and coronary arteries, and to the stroke of the apex upon the ribs. This is an appearance that, as it belongs to this complaint, might be useful in a case otherwise dubious, if any such should occur, to aid in deciding whether the action of the heart had been inordinate.

The heart was enlarged to double its usual size, as we judged with confidence, for pains had been taken to examine hearts in a healthy state, for the purpose of forming a comparison. Its firmness was not proportioned to its bulk, but it was considerably flaccid. Near the apex, over the left ventricle, was a soft spot, similar to that found in the preceding case. The venæ cavæ were then divided, and a torrent of black blood issued from each of the orifices, in spite of our efforts to restrain it. All the cavities of the heart were filled, as we afterwards saw, with similar blood; in which circumstance this resembles the other cases; though in this case the blood was entirely fluid, and thinner than in cases of different disease: whereas, in every other instance, was partly or wholly coagulated. This therefore must be considered as another appearance peculiar to this complaint, because it is well known, that blood is not usually found in the left cavities of the hearts of those who die of other disorders. The cause of it is doubtless an obstruction, which opposes the free discharge of blood from the heart, whether that obstruction be in the aortal valves, in the aorta itself, or in the disproportion between the heart, or more precisely the left ventricle, and the parts it supplies with blood.

Why was the blood entirely fluid in this case? If we compare the appearance of the cellular membrane, and of the lungs, in both of which there was a deficiency of blood, with the aspect of the face, where there was an accumulation of blood, and consider at the same time the mode of termination of this case, we shall find reason to believe, that death was produced by a violent pressure of the brain from a congestion of blood in its vessels, in consequence of the obstruction to the return of that fluid to the heart. An additional proof of this opinion is derived from the great quantity of blood, which poured from the vena cava superior, during the whole time of the examination, and afterward; so that it was found impossible to preserve the subject from the blood flowing between the ligatures, notwithstanding the thorax was entirely emptied, before it was closed. In cases of sudden death from apoplexy, related by Morgagni, the blood was frequently fluid, and this may be supposed to be the cause of that appearance in the present case. The extraordinary thinness or watery state of the blood is a distinct circumstance, which will be presently noticed.

An examination of the brain, to ascertain the truth of the supposition above mentioned, was relinquished with regret, but this was impracticable; for the want of time on these occasions frequently obliged us to content ourselves with investigating the state of the most important parts. This must serve as our apology for not oftener relating the appearance of all the principal organs; yet it should be observed, that such methods have been employed to ascertain with accuracy the most interesting morbid phœnomena, as would satisfy the most scrupulous anatomist.

The tricuspid valves and the semilunar valves of the pulmonary artery had lost their healthy transparency, but were not otherwise diseased. In all the above cases these valves had been found without important derangement of their structure; a circumstance not less remarkable, than difficult to be satisfactorily explained. The basis of the mitral valves was marked by a bony projection, which nearly surrounded the orifice of the ventricle; the valves themselves were thickened, and one of them was smaller than the other. The semilunar valves of the aorta were lessened in size, and somewhat thickened. One of them was ossified sufficiently to annihilate its valvular function; the others were slightly. The aorta under the valves was semicartilaginous, ossified in one small spot, roughened by fleshlike prominences in others, entirely deprived of the smoothness of its internal coat, and in size proportioned to the heart.

The parietes of the heart were thicker than those of a healthy heart, but thin when compared with its whole volume; whence it follows, that the cavities were enlarged. That of the left ventricle was disproportionately larger than the others, but no difference of size could be ascertained between the auricles. When a cavity of the heart is situated in the course of the circulation immediately behind a contracted orifice, it seems probable that the contraction may have an important influence in originating the enlargement or aneurism of that cavity; but, where there is no contraction of an orifice, what is the obstruction which impedes the free discharge of blood from the heart, and causes the first yielding of its parietes? Perhaps a violent simultaneous action of many muscles, from great exertion, may, during the systole of the heart, impede the passage of the blood through the arteries, drive it back upon the valves of the aorta, and resist the heart at the moment of its contraction. If the parietes of the heart yield, in one part, it is easy to conceive a consequent distension of the remainder to any degree; for, during the systole of the heart, the columnæ approximate, till their sides are in contact, to protect the parietes of the heart; but, if these be distended, the columnæ can no longer come in contact with each other, and the blood passing between them will be propelled against the parieties, and increase their distention. The left ventricle being thus dilated, the mitral valves will not be able to completely cover its orifice, and part of the blood will escape from the ventricle, when it contracts, into the auricle when dilated with the blood from the lungs; and this undue quantity of blood will gradually enlarge the auricle. A resistance will arise, from the same cause, to the passage of the blood from the lungs, thence to that from the right ventricle and auricle, and thus these cavities may become enlarged in their turns. When an ossification of the aorta, or of its valves, exists, there will be a resistance to the passage of the blood from the left ventricle, either by a loss of dilatability in the artery, or a contraction of the orifice by the ossified parts. In either case, the blood will reflow upon the heart, and dilate the left ventricle, as in [case the first], and others; and, if the mitral valves be thickened and rigid, the left auricle will be more dilated than in a case of simple aneurism of the left ventricle, as appeared also in the [first case].

The coronary arteries, at their origin from the aorta, and a considerable distance beyond, were ossified. How far does the existence of this ossification in this and other cases related by different authors, without symptoms of angina pectoris, disprove the opinion that it is the cause of that disease?

The abdomen being opened, the organs generally appeared sound, except the liver, which had its tunic inflamed, its substance indurated and filled with blood. The vestiges of inflammation in the coat of the liver were traced in every instance already related, while at the same time the liver, in all, appeared shrunken. The diminution of size in the liver, after death, cannot at present be well explained; for it is very certain that such a diminution is not an attendant of this disorder, during most of its stages, but that on the contrary a state exists precisely opposed to it. The indications of distention of the liver, clearly perceived in some cases, have been pain, tenderness, and sense of distention, in the right hypochondrium, and, what is less equivocal than these, very considerable swelling and prominence of the liver. The inflammation of its tunic is an effect of this distention and of the consequent pressure against the adjacent parts.

The cause of this phœnomenon can easily be explained. If an obstruction exist in either side of the heart, or in the lungs, the blood to be poured into the right auricle, from the vena cava inferior, must be obstructed, its flow into that vessel from the liver will be equally checked, the thin coats of the hepatic veins and of the branches of the vena porta will yield and distend the soft substance of the liver. Hence are caused the discharges of blood from the hæmorrhoidal veins, which form one of the characteristic symptoms of the disease; for as these vessels empty their blood into the meseraic veins, which open into the vena porta, if the meseraic veins be obstructed, the hæmorrhoidals must consequently be also affected, and they easily burst open from too great distention. The hæmoptoe, which also is so frequent, is as easily explained on the same principle.

The cause of the serous collections is not so readily discovered. In this case, as in most of the others, we found a considerable quantity of water in the abdominal cavity. Dropsy is commonly considered as a disease of debility, but in these cases it often appeared, while the strength was unimpaired, and the heart acted with very extraordinary force. If the blood was driven with rapidity through the arteries, while an obstruction existed at the termination of the venous system in the heart, the consequences must have been accumulation in the venous system, difficult transmission of the blood from the extreme arteries to the veins, overcharge of the arterial capillary system, consequent excitement of the exhalant system to carry off the serous part of the blood, for which it is adapted, and thence a serous discharge into the cavities, and also on the surface of the body; for great disposition to sweating is a common symptom. In addition to these, there is another cause of the universality of these effusions. The blood, in all the cases which I have examined, is both before and after death, more thin and watery than healthy blood. How this happens, our knowledge of the theory of sanguification does not enable us to determine. Perhaps, as the imperfect respiration must cause a deficiency of air, and consequently of oxygen, in the lungs; and as the absorption of oxygen is a cause of solidity in many bodies, this tenuity of the blood may proceed from a deficient absorption of oxygen. However this may be, it is certain that the blood is very much attenuated, though with considerable variations in degree, as it is sometimes found thin on opening a vein, and at a subsequent period is thicker; varying perhaps according to the continuance of ease or difficulty in respiration. It is certain, that this attenuation of the blood must tend to an increase of the serous exhalations.

That these secondary dropsies are not the effect of debility appears pretty evident from considering, that they often exist while the strength of the patient is yet undiminished, while all the other secretions, except that of the urine, are carried on with vigour, and while the appetite and digestive functions are not only unimpaired, but improved.

The examinations of the [ninth] and [tenth] cases are particularly valuable, because they confirm what had been observed in other subjects; they exhibit two well marked instances of aneurism of the heart, and present us a view of organic disease unattended by dropsy of the pleura. This must be sufficient to remove the suspicion, that the symptoms we have attributed to the former disease might arise from the existence of the latter. No one probably will be willing to impute a chronic disease, terminated by a sudden death, to five or six ounces of water in the pericardium; for such a quantity, though it might produce inconvenience, could not prove fatal, unless it were suddenly effused; and, if this were true, it of course could not have been the cause of the long train of symptoms observed in [case tenth].

Dr. William Hamilton, the author of a valuable treatise on the digitalis purpurea, thinks the hydrothorax a more frequent disease than has commonly been imagined, because he conceives that it has often been mistaken for organic disease of the heart. He names, with some precision, many symptoms of the latter complaint; but how remote he is from an accurate knowledge of it may be discovered by his opinion, that, in diseases of the heart, “the patient can lie down with ease, and seldom experiences much difficulty of breathing.” The limits of this paper do not admit a discussion of this and other points, respecting which he seems to be mistaken. We must therefore submit them to be decided by the evidence adduced in Dr. Hamilton’s “observations,” and by that which may be drawn from these cases, and future investigations of the subject. It will perhaps hereafter appear surprising, that derangements in the structure of so important an organ as the heart should have been lightly estimated by very respectable authors.

While concluding these observations, a case of this disease presented itself, which comprehends so many of the symptoms, that I cannot neglect an opportunity of recording it, especially as it exhibits the complaint in an earlier stage than the others, with appearances equally unequivocal. I may here be allowed to remark, that no cases have been introduced which occurred before my attention was directed to a close observation of this disorder, and that there are many others, under the care of practitioners of eminence belonging to this society, with symptoms perfectly well marked, which it has not been thought necessary to adduce. In proof of this, reference may be had to Dr. Warren, sen. who has a number of cases, and also to Dr. Dexter, Dr. Jackson, and Dr. J. C. Howard.

A lady from the country, of a robust habit, whose age is about thirty-four years, complains of uneasiness in the right side below the edge of the ribs, sometimes attended with swelling, external soreness, and a throbbing pain, which often reaches to the shoulder, and produces a numbness of the right arm. She is rather uncertain at what time her complaints commenced. About two years since she lost her husband, and was left with but small means to support a number of children. She became in consequence, much dejected. While nursing a child, about a year since, she first was sensible of palpitations of the heart, which, in about three months, were followed by dyspnœa very much augmented by ascending an eminence; and profuse discharges of blood from the mouth, first raised, she believes, by vomiting, and afterwards by coughing. Evacuations of blood from the hæmorrhoidal vessels appeared about the same time, and occasionally since, till within six weeks, during which time there have been no sanguineous discharges, and this suppression has aggravated her other complaints.

The pulsation of the heart is felt most distinctly quite on the left side of the thorax, where there is a painful spot; it is perceptible also in the epigastric region. It is irregular and variable, at one moment hard, strong, distinct, and vibrating; at another, feeble and confused. There is also sometimes perceived a pulsation above the left clavicle, within the insertion of the mastoid muscle, commonly attended with a visible fulness of the superior part of the breast. The thorax feels, to the patient, as if it were girt across, and there is a distinct pain in the heart. Both these sensations are aggravated by a very hard, frequent, and dry cough, which however begins to be less violent from the use of the scilla maritima. The countenance is animated, and rather flushed, but not so much overcharged with blood as happens in many instances; perhaps it little exceeds a blush, so moderate that it might be considered as an indication of perfect health; yet the head is greatly disturbed with dizziness, and frequent and intense pain, and is seen to be shaken by the palpitations.

The functions of the abdominal viscera are not much deranged. The appetite varies, though it is commonly good; the intestinal evacuations, and the menstrual discharges, are regular; the urine is turbid, and so small in quantity as sometimes to produce strangury. The abdomen and inferior extremities are swelled, and the distention produces an uneasiness in the former, and pain and a livid colour about the gastroenemii muscles in the latter. The pulse is hard, without strength or fulness, slightly intermittent, variable, and irregular; yet it has not so much irregularity as in most of the cases recorded above.

This patient is uneasy in bed, though she raises her head almost upright; her sleep is disturbed by unpleasant dreams, and by startings, sometimes quite to an upright posture, without any cause discoverable to herself. She can incline a little to the left side, but never to the right, because it brings on a singular oppression, and a sense of weight drawing on the left side. When most distressed by dyspnœa she bends her head and trunk forward, and remains thus seated a considerable portion of the night, often sighing quickly and convulsively. She is subject to profuse sweatings, and very liable to take cold, and is then more uneasy.

This lady is still corpulent. She has taken much medicine, under the direction of eminent physicians, sometimes with temporary relief, but most commonly without any. The exercise of walking slowly, in pleasant weather, although it increases the palpitations at the moment, is followed with relief from the distressing feelings, which are increased when she sits still for a long time. She has no suspicion of her hopeless situation, and confidently expects relief from medicine, yet labours under a melancholy which is unnatural to her.
