Left atrial appendage aneurysm, either congenital or acquired, is a very rareanomaly. It is caused by congenital dysplasia of the atrial muscles, or it may be theresult of other systemic or heart diseases.This anomaly is mostly asymptomatic and usually diagnosed incidentally, butoccasionally it may present with atrial tachyarrhythmias and/or thromboembolicevents.This report describes the case of a patient with giant congenital aneurysm of theleft atrial appendage.
