Left atrial appendage aneurysm-a rare anomaly with an atypical presentation

Congenital Heart Disease

Abstract

Left atrial appendage aneurysm (LAAA) is a rare condition caused by congenital dysplasia of the atrial muscles. Patients usually present with atrial tachyarrhythmias as a result of ectopic foci of atrial rhythm generation or systemic thromboembolism. We report a case of a 38-year-old Native American female presenting with 1-month history of cough, in sinus rhythm, and found to have a large cyst-like structure next to the left ventricular lateral wall on transthoracic echocardiography. This structure was later confirmed as a LAAA on cardiac magnetic resonance imaging. Patient underwent aneurysmectomy without any complications.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
