A morphometrical study of myocardial disarray associated with 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.

Right ventricular pacing for right ventricular outflow tract obstruction in a man with biventricular hypertrophic cardiomyopathy.

A 40-year-old man with known hypertrophic cardiomyopathy presented with syncope after coughing. Physical examination revealed a systolic murmur that was accentuated by the Valsalva maneuver. An electrocardiogram suggested biventricular hypertrophy and biatrial enlargement (Fig. 1). Echocardiograms revealed asymmetric septal hypertrophy with a diastolic septal thickness of 2.3 cm, and evidence o...
