We report a successful case of external conduit operation in a 7.2 kg male infant. A 17-month-old boy was admitted because of increasing cyanosis and polycythemia. He had undergone classical Blalock-Taussig shunt at the age of 51 days with the diagnosis of tetralogy of Fallot with pulmonary atresia. ⋯ We chose external conduit operation and correction of the right pulmonary artery stenosis instead of additional shunt and correction of the stenosis with cardiopulmonary bypass. He is in a good postoperative condition. It is preferable that external conduit operation is applied to similar infant cases from the standpoint of exercise ability, myocardial degeneration and postoperative arrhythmia.
