Left Ventricular Aneurysmectomy in a Young Female of Unknown Etiology with Pseudoaneurysm: A Case Report

Abstract

A left ventricular pseudoaneurysm is formed when there is free wall rupture of the myocardial wall with discontinuity and roof covered by pericardium mural thrombus or fibrous tissue without any myocardium. A left ventricular pseudoaneurysm is a rare and life-threatening event. We report a young 22-year-old female with unknown etiology of a pseudoaneurysm, who was previously managed as a psychiatric case and for musculoskeletal pain. On subsequent investigation and confirmation with cardiac magnetic resonance imaging, aneurysmectomy was done. This is a rare case in a young 22-year-old woman with a ventricular pseudoaneurysm of unknown etiology. Considering the high risk for rupture of a ventricular pseudoaneurysm, surgical resection was mandatory with no complications intra- and post-procedure.

“…2 Two case reports found in the literature demonstrated a left ventricle pseudoaneurysm with an unknown aetiology in young patients. 3 By definition, the wall of left ventricle pseudoaneurysms do not contain endocardium or myocardium, as opposed to true aneurysms where the wall consists of all the layers (endocardium, myocardium and epicardium). Due to such cardinal difference in wall structure between them, differentiation is essential to determine an appropriate method of management and can explain the high risk of rupture reaching 30-45% 4 if the pseudoaneurysm is left untreated surgically.…”
