Predominant, severe right ventricular outflow tract obstruction in hypertrophic cardiomyopathy.

Recently, new cardiac imaging techniques as cardiac magnetic resonance have shown to play a primary role for a recognition of unusual mechanisms of right and left ventricular obstruction. However, echocardiography remains the most widely used technique and the first step to recognize myocardial hypertrophy, blood flow velocity, and pressure gradients in real time (2). We describe a rare case of hypertrophic cardiomyopathy with isolated obstruction of right ventricular out flow where transthoracic echocardiography was able to detect right ventricular hypertrophy and obstruction.
