Valvular Heart Disease Information
What is Valvular Heart Disease
Although most cases of valvular disease in the United States were at one time due to rheumatic heart disease (still true in developing countries), other causes are now more common. The typical findings of each lesion shows how to use bedside maneuvers to distinguish murmurs.
Echocardiography yields information about valve morphology, left ventricular mass and function, and atrial and ventricular chamber size. Doppler ultrasound provides quantitative measurements of transvalvular gradients and pulmonary artery pressure and gives more qualitative estimates of valvular regurgitation. The prevalence of mild or even moderate valvular regurgitation is not small, and care must be taken not to overestimate the importance of these findings. Transesophageal echocardiography (TEE) often provides improved image quality. Valve morphology (particularly with prosthetic valves), vegetations, thrombi, and eccentric regurgitant jets are more easily identified with TEE.
The now withdrawn diet medications fenfluramine and dexfenfluramine may be associated with valvular heart disease, but whether these agents cause clinically significant valvular abnormalities remains controversial. Recent data suggest that this is, if anything, a rare occurrence.
