[The superior approach technique for total anomalous pulmonary venous return (type I b)]

Two infants with total anomalous pulmonary venous return (type I b) were operated on successfully through the superior approach. The technique of anastomosis was designed for making large anastomosis between the common pulmonary vein and left atrium according to each pattern of pulmonary venous drainage. In these patients, the angiocardiogram at one year after the operation showed no stenosis between pulmonary vein and left atrium and electrocardiogram revealed no arrhythmias, postoperatively. The operative procedures which used in these patients are described.
