Contained rupture of left ventricular false aneurysm after acute myocardial infarction secondary to left anterior descending artery embolism.

Left ventricular free wall rupture is a rare complication of acute myocardial infarction and accounts for a significant number of fatalities. Pseudoaneurysm is a variety of left ventricular rupture whereby the pericardium seals the defect, forming the wall of the pseudoaneurysm. The diagnosis is usually confirmed with echocardiography, and emergent surgical repair is required in suspected impending rupture. The present report describes the case of a 58-year-old woman who presented with a myocardial infarction due to distal left anterior descending artery occlusion, complicated by ventricular pseudoaneurysm with impending rupture. The patient had an otherwise normal coronary tree.
