OTHER LESIONS

Tricuspid insufficiency, except as rarely found in the fetus, is generally due to a relative insufficiency rather than to an actual disease of the tricuspid valve. In other words, if the right ventricle dilates the valve may be insufficient. Tricuspid stenosis, pulmonary stenosis and pulmonary insufficiency are rare, and are probably nearly always congenital.

The diagnosis as to whether the murmurs heard in the heart are hemic, functional, accidental, or indicative of valvular lesions would be without the scope of this book. It is always presumed that a correct diagnosis has been made, or at least a presumptively correct diagnosis. Frequently more than one murmur and more than one lesion in a heart are present. Often one murmur denotes a permanent lesion, and another may be one that will become corrected when compensation is improved.
