Coronary artery anomalies are common among patients with tetralogy of Fallot. One hundred and thirty-five patients (80 males and 55 females) with tetralogy of Fallot who underwent repair between 1995 and 2002 were studied to determine the incidence of coronary anomalies in Iranian patients. Eight (5.9%) patients (4 males and 4 females) had a surgically relevant coronary artery anomaly: single coronary ostium in 5, origin of the left anterior descending artery from the right coronary artery in 2, and origin of the right coronary artery from the left coronary artery in 1. The surgical technique in 3 of these patients was repair of the ventricular septal defect with a transverse incision on the right ventricle, without damage to the coronary arteries. In another patient, an allograft aortic valve cylinder was inserted. In the other 4 patients with a single coronary ostium, placement of a limited transannular patch was adequate. Consideration of these anomalies during primary repair could decrease the risk of operation in such patients. However, it seems that the presence of anomalous coronary arteries does not affect incremental risk after surgical repair.
