Acquired right ventricular outflow tract obstruction

Acquired right ventricular outflow tract obstruction.

I t is not unusual for complicated aneurysms of the ascending aorta to affect left ventricular function. Processes causing or associated with an aneurysm may narrow the coronary artery ostia and produce myocardial ischemia or infarction; the aneurysm may distort the aortic valve ring and produce aortic insufficiency with subsequent left ventricular hypertrophy, dilatation, and failure. However,...

Right ventricular myxoma causing right ventricular outflow tract obstruction.

Cardiac myxomas are the most common neoplasms of the heart. They can be located in any chamber of the heart but frequently in the left atrium. In this report we present a patient who had been treated for a right ventricular myxoma originating from the interventricular septum and leading to right ventricular outflow tract obstruction.

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...
