Left ventricular apical aneurysm as a consequence of diffuse type congenital nonfamilial supravalvular aortic stenosis in a 30-year-old female.

Abstract

Congenital nonfamilial supravalvular aortic stenosis (SVAS) is relatively rare, its diffuse type being the least common. We present a 30-year-old woman with diffuse SVAS complicated with left ventricular apical aneurysm. We believe that subtle left ventricular myocardial ischemia or infarction and long-lasting severe pressure overload to the apical chamber caused LV apical aneurysm in our case. Acquired LV apical aneurysm secondary to supravalvular aortic stenosis, in the absence of atherosclerotic coronary artery disease and hypertrophic obstructive cardiomyopathy, has not been described before.
