title: Calcific aortic stenosis presenting as acute myocardial infarction.
abstract: A previously asymptomatic 38-year-old male with calcific aortic valve stenosis (instantaneous peak-to-peak systolic gradient: 46 mmHg) suffered an acute myocardial infarction. Coronary arteriography revealed an obstruction in a distal branch of the left circumflex artery. Left ventricular angiography demonstrated impairment of contraction of the lateral wall. We suggest that the myocardial infarction was the result of calcific embolism from the calcified aortic valve stenosis and may occur as a first manifestation of the disease.
