Two Cases of Total Anomalous Pulmonary Venous Return of the Supracardiac Type with Stenosis Simulating Infradiaphragmatic Drainage

Abstract
Two patients who died during the neonatal period with congestive heart failure and marked pulmonary congestion were found at autopsy to have total anomalous pulmonary venous return of the supracardiac type with stenosis of the pulmonary vein. The narrowing was the result of an unusual course of the vein, which passed between the left pulmonary artery and left main bronchus and was stenosed at this point. It is emphasized that the clinical and x-ray findings were indistinguishable from those of total anomalous pulmonary drainage below the diaphragm.
