Abstract
Four cases of congenital coronary arteriovenous fistula were diagnosed using coronary angiography. Three cases had fistula-related chest pain and the remaining case showed no symptoms but displayed electrocardiographic changes suggesting myocardial ischemia. As he was elderly and had a potential for future complications, we decided to close the fistulas of all cases. Three cases were closed with transcatheter coil embolization and one with surgical ligation due to a suspicious accompanying pericardial cyst. None of the patients demonstrated periprocedural or perioperative complications and all were relieved from symptoms during the 2 year follow-up period. We concluded that transcatheter coil embolization and surgical ligation are effective methods for use in the management of coronary arteriovenous fistula.
