Abstract

While Doppler echocardiography has become the gold standard for the diagnosis of hypertrophic cardiomyopathy, there are many pitfalls in its use. Some of these pitfalls are technical in nature resulting from inadequate image quality, incorrect transducer angulation, and improper equipment settings. Other pitfalls relate to the diversity and heterogeneity in defining hypertrophic cardiomyopathy and to the host of disorders that may mimic it by echocardiography. The pattern and extent of ventricular hypertrophy, systolic anterior motion of the mitral valve, and Doppler determination of left ventricular outflow tract obstruction, diastolic dysfunction, and mitral regurgitation are discussed, as are wall-motion abnormalities and myocardial echo reflectivity. While these echocardiographic features of hypertrophic cardiomyopathy are nonspecific when seen in isolation, their combined presence in the appropriate clinical setting makes the diagnosis likely.
