Surgical repair of a coronary artery aneurysm associated with coronary artery fistula - a case report

Coronary artery aneurysm is a relatively rare disorder that is usually discovered as a secondary finding in patients undergoing coronary artery angiography. Coronary artery fistulas are relatively more frequent than rare aneurysms and are often associated with other cardiac abnormalities. The etiology of aneurysms is mostly atherosclerotic, and they are less frequently associated with other acquired or congenital diseases, such as Kawasaki disease, connective tissue diseases, septic emboli, arteritis, and iatrogenic disease. We report a 70-year-old woman with a rare combination of a coronary artery aneurysm associated with a coronary artery fistula, which drained into the pulmonary artery. The diagnosis of our patient was made by selective coronary angiography and confirmed by computed tomography angiography. The patient was treated surgically because of the symptomatic course of the disease.
