The infradiaphragmatic type of Total Anomalous Pulmonary Venous Return(TAPVR) is a rare congenital cardiac anomaly which usually results in death during the period of early infancy. A two month-old baby boy with cyanosis and respiratory distress was suspected of having a TAPVR clinically and two-dimensional echocardiographic findings were compatible with the infradiaphragmatic type of TAPVR. The subsequent cardian catheterization and dineangiogram revealed the common pulmonary vein conected with portal vein and inferior vena cava in the infradiaphragmatic area with obvious obstruction. The surgery and the autopsy confirmed the preoperative diagnosis. Among infants presenting pulmonary venous congestion in the newborn period, TAPVR below the iaphragm should be one of the important diagnostic considerations.
