OBJECTIVES: Early atresia of the common pulmonary vein (ACPV) leads to total anomalous pulmonary venous drainage, while late atresia or incomplete absorption leads to common pulmonary vein atresia and cor triatriatum sinister (both of which are rare). We report seven cases of atresia of the common pulmonary vein at autopsy. DESIGN: Retrospective case records studied. SETTING: Tertiary care teaching hospital affiliated to medical college in Mumbai, India. PATIENTS AND METHODS: The clinical and autopsy records of neonates and infants diagnosed with ACPV over a period of 11 years were reviewed. The demographic data, clinical features, and results of investigations were correlated with the cardiac findings at necropsy. RESULTS: Seven neonates and infants (five males and two females) had ACPV. Six babies presented at birth and expired within 48 hours. They had a homogeneous group of symptoms of cyanosis since birth with respiratory distress and/or features of congestive cardiac failure. One had perimembranous ventricular septal defect with bicuspid pulmonary valve and atresia of aortic valve. Two had dysmorphic facial features suggestive of Down's syndrome. Isolated ACPV was seen in only two patients. Asplenia syndrome was seen in three patients. Marked dilatation of the pulmonary lymphatics was identified in three patients. CONCLUSIONS: Early atresia of the common pulmonary vein, an extremely rare abnormality, manifests in early infancy/neonatal period and needs urgent corrective surgery. It is associated with other congenital heart disorders and extracardiac manifestations as well.
