Acute myocardial infarction caused by coronary embolism complicated by left ventricular free wall rupture.

Abstract Acute myocardial infarction with normal coronary arteries is a relatively infrequent finding. This report describes a rare combination of an embolic event to a normal coronary artery, presumably originating from a left atrial thrombus. An anomalous origin of the infarct-related coronary artery presumably enabled preferential penetration of the clot into the artery. The infarction was further complicated by rupture of the left ventricular free wall. (J Am Soc Echocardiogr 2001;14:754-6.)
