Abstract

An unconscious 79-year-old woman was admitted. Echocardiography showed cardiac tamponade with pericardial effusion. Enhanced computed tomography revealed pericardial effusion and a coronary artery aneurysm (maximum diameter of 16 mm) on the left side of the main pulmonary artery. Emergency coronary angiography confirmed the aneurysm, which originated from a branch of the left anterior descending artery. Emergency surgery was performed through median sternotomy with cardiopulmonary bypass. After cardiac arrest by antegrade cardioplegia, the aneurysm was opened and two orifices of the arteries were observed. The orifices were ligated, and the remaining aneurysmal wall was closed with a continuous suture. A pathological examination of the aneurysmal wall demonstrated an atherosclerotic true aneurysm.
