Abstract

Echocardiography is an important tool for the diagnosis of valvular diseases such as mitral stenosis, mitral valve prolapsed, flail mitral leaflet, mitral regurgitation, tricuspid stenosis, Ebstein’s anomaly, aortic stenosis, pulmonary stenosis, and pulmonary regurgitation. Often valvular disease is suspected clinically because of a murmur especially if coupled with suggestive symptoms such as dyspnoea and palpitation on exertion. A murmur is a sound caused by turbulent blood flow due to high volume flow across a normal valve, high velocity flow across a stenotic valve, or regurgitant flow from an incompetent valve. Echocardiography can confirm the site of origin of a murmur detected clinically. It can image a diseased valve and detect an abnormal pattern of blood flow on color flow mapping. It can also reveal the etiology of the valvular disease, quantify its severity and assess its effect on dimensions of cardiac chambers and on ventricular function. This chapter discusses the echo features of various valvular diseases, with due emphasis laid on pitfalls in diagnosis, their causation, and indications for surgical intervention in various valvular diseases.
