Abstract

Hypertrophic cardiomyopathy (HCM) has diverse pathophysiological and clinical features, according to the extent and severity of the hypertrophy development. Hypertrophy mostly involves the left ventricle and sometimes causes a left ventricular outflow tract obstruction. Right ventricular involvement is less frequent, and even the severe form of a right ventricular outflow tract (RVOT) obstruction by concurrent right ventricular hypertrophy in a patient with HCM is rare. We report a case of biventricular HCM with a clinically, morphologically, and hemodynamically significant RVOT obstruction, which had been treated successfully with surgical myectomy.
