We experienced 5 neonates with total anomaious pulmonary venous connection, includidng one with common pulmonary vein atresia. Alll babies but one had cyanosis and tachypnea soon after birth. Chest x-ray showed small heart and fine reticular shadowing in the lung fields. Preoperative pulmonary arterial pressure was high as same as the systemic level in all babies, and pulmonary vein pressure was 27-44 mmHg. The operation was performed 2-19 (9±9) days of life and body weight at the surgery was 2.5-3.3 (2.7±0.3) kg. Total circulatory arrest was used in 4 babies. Three of them survived the operation, and two died. One was operated upon under the cardio-pulmonary bypass without total circulatory arrest and reguired the longest aortic cross clamping time, dying to low cardiac output and sepsis. The other died of severe low cardiac output due to myocardial rupture during operation.
