RESUMEN
An infant having parents of Jehovah s Witnesses was 4 months old and 5.6 kg in weight. Echocardiographic diagnosis was complete transposition of great arteries(TGA), ventricular septal defect(VSD), atrial septal defect(ASD), patent ductus arteriosus(PDA), and bilateral superior vena cava(SVC). The preoperative hemoglobin level was 14.9 g/dl. We performed an arterial switch operation(ASO) with VSD closure without transfusion and he was discharged uneventfully 16 days after the operation. At that time the hemoglobin level was 12.8 g/dl. We report that we could successfully correct the complex congenital heart disease without transfusion by the combined use of erythropoietin and aprotinin, intraoperative meti-culous hemostasis, and postbypass ultrafiltration.
