An Incidentally Discovered Large Left Main Coronary Artery Aneurysm

Abstract

Left main coronary artery aneurysms (LMCAA) are rare. The most common cause is atherosclerosis followed by congenital malformations. Patients with LMCAA can present with shortness of breath and angina if there is coexisting obstructive coronary artery disease. Here we describe a patient incidentally found to have a 2 cm aneurysm of the left main coronary artery in the setting of an ST-elevation myocardial infarction (STEMI) and we discuss potential medical and surgical treatment options for this incompletely understood condition.

Keywords: left main aneurysm; left main coronary artery aneurysm.
