A giant aneurysm of the left atrial appendage in childhood

Abstract

Congenital aneurysm of the left atrial appendage is a very rare cardiac anomaly which can be accompanied with supraventricular rhythm disorders and life-threatening systemic thromboembolism. In this article, we present a six-year-old girl with a bulky mass of soft tissue density on the cardiac wall in chest X-ray which was adjacent to the left atrial appendage in two-dimensional transthoracic echocardiography. The patient was diagnosed with the left atrial appendage aneurysm. Surgery was performed to eliminate potential complications. The patient was uneventful in the postoperative follow-up.
