Surgical management of an aneurysm of the left atrial appendage to prevent potential sequelae

An aneurysm of the left atrial appendage is an extremely rare anomaly that is commonly associated with supraventricular arrhythmia, compression of the coronary arteries, intracardiac thrombus and pulmonary venous stenosis. This condition may be caused by congenital dysplasia of the musculi pectinati...

description An aneurysm of the left atrial appendage is an extremely rare anomaly that is commonly associated with supraventricular arrhythmia, compression of the coronary arteries, intracardiac thrombus and pulmonary venous stenosis. This condition may be caused by congenital dysplasia of the musculi pectinati and is usually diagnosed in the second to fourth decades of life. We report the surgical management of an asymptomatic 9-year old girl with this anomaly. She was referred to us because of abnormal chest X-ray findings, and investigation revealed an aneurysm of the left atrial appendage. As this condition may have potentially fatal complications, the aneurysm was completely resected under cardiac arrest with cardiopulmonary bypass to prevent recurrence and thrombus formation. We suggest that resection of an aneurysm of the left atrial appendage under cardiac arrest with cardiopulmonary bypass is a reasonable treatment option to prevent potential complications, particularly in children.
