An Unusual Case of a Giant Left Ventricular Pseudoaneurysm

Abstract

Left ventricular pseudoaneurysm is one of the late mechanical complications of myocardial infarction, which also can be associated with cardiothoracic surgery, trauma, and, rarely, infective endocarditis. A giant pseudoaneurysm is a rare presentation. We report a patient with a giant left ventricular pseudoaneurysm probably following a silent myocardial infarction, who presented with congestive heart failure symptoms. Unfortunately, cardiac rupture and tamponade developed during diagnostic studies. The patient had surgical repair of the aneurysm and the mitral valve, but could not recover fully after surgery. We suggest urgent surgery whenever a giant left venricular pseudoaneurysm is diagnosed.
