Noncompaction of left ventricular myocardium in the presence of calcific aortic stenosis in an adult.

ABSTRACT

We describe an adult patient with a hitherto unreported association of severe aortic stenosis with extensive noncompaction of the left ventricular myocardium without any hypertrophy; however, there was severe left ventricular systolic dysfunction in the presence of a normal-sized left ventricular cavity on two-dimensional echocardiography. This condition was differentiated from persistence of embryonic intramyocardial sinusoids by selective coronary angiography.
