Large Congenital Left Atrial Appendage Aneurysm in an Adult

Abstract

Left atrial appendage aneurysm is a rare cardiac abnormality predisposing to atrial arrhythmias and thromboembolic phenomena. When discovered, surgical management is the treatment of choice. Here we describe a case of incidentally discovered large congenital left atrial appendage aneurysm in a young adult that was treated with surgical resection.
