Bilateral partial anomalous pulmonary venous connection; report of a case

We have experienced a case of bilateral partial anomalous pulmonary venous connection with a fossa ovalis type of atrial septal defect and pulmonary stenosis. The right upper pulmonary vein returned to the superior vena cava and the left upper pulmonary vein returned to the left innominate vein via the vertical vein. The atrial septal defect was enlarged and the right upper pulmonary vein was baffled into the left atrium with an equine pericardial patch. The left upper pulmonary vein was divided and anastomosed to the left atrial appendage. Pulmonary commissurotomy was also done for concomitant pulmonary stenosis. Postoperative course of the patient was excellent with constantly normal sinus rhythm. Angiography 2 weeks after operation showed no evidence of pulmonary venous obstructions on both sides.
