Long-term results of surgery for coronary artery fistulas.

This report describes our long-term result of surgery for coronary artery fistula in 12 patients. Follow-up range was from one year to 15 years, and with one exception they were all congenital in origin. Diagnosis was confirmed with angiography in all cases, showing single fistulous tract in four patients and multiple in eight patients. All but one patient were operated on by cardiopulmonary bypass with no mortality and with complete resolution of symptoms and no recurrence of the fistula. We conclude that surgery for coronary artery fistula can be accomplished safely with excellent long-term results and should be recommended for all patients to prevent life-threatening complications that may develop.
