The infradiaphragmatic type of Total Anomalous Pulmonary Venous Return(TAPVR) is a rare congenital cardiacanomaly which usually results in death during the period of early infancy. A two month-old baby boy with cyanosisand respiratory distress was suspected of having a TAPVR clinically and the two-dimensional echocardiographicfindings were compatible with the infradiaphragmetic type of TAPVR. The subsequent cardiac catheterization andcineangiogram revealed the common pulmonary vein connected with portal vein and inferior vena cava in theinfradiaphragmetic area with obvious obstruction. The surgery and the autopsy confiremd the preopeative diagnosis.Among infants presenting pulmonary venous congestion in the newborn period. TAPVR below the diaphragm shold be oneof the important diagnostic cosiderations.
