Resolution of Thrombi in Left Atrial Appendage Aneurysm

Atrial appendage aneurysm is a rare cardiac disease and may be complicated by embolic events and rhythm disturbances. We describe a case of a congenital left atrial aneurysm presenting with a cere-brovascular accident in a 57-year-old female. The diagnosis was made by transesophageal echocardiography, which revealed the presence of intraaneurysmal thrombi. The patient initially received anticoagulant therapy and the thrombi were resolved. Subsequently, she was successfully operated on and the aneurysm was removed. This is the first report of thrombi resolution in a left atrial appendage aneurysm.
