CONGENITAL CORONARY-ARTERY FISTULA - SURGICAL RESULTS AND LATE CHANGES IN CORONARY-ARTERY ANEURYSM

Four pediatric cases of congenital coronary artery fistula were surgic ally treated and followed for 8 years. In the 3 cases of right coronar y artery to right ventricle fistula, regression of coronary artery dil atation was observed postoperatively. In the 1 case of circumflex arte ry to right atrium fistula, aneurysmal dilatation of the abnormal vess el persisted for 8 years. A reduction in vessel size is expected if th e fistula-related coronary artery has a normal course and normal branc hings. When the aneurysmal vessel takes an abnormal course without bra nches, it should be removed surgically along with fistula closure.
