Partial anomalous pulmonary venous connection and partial atrioventricular septal defect in an adult: Report of a case.

A partial anomalous pulmonary venous connection (PAPVC) associated with partial atrioventricular septal defect (AVSD) is a rare combination. A 51-year-old man who experienced dyspnea on exertion was found to have a PAPVC with the middle portion of the superior vena cava and a comorbid partial AVSD. A patch diversion was successfully performed using an expanded polytetrafluoroethylene patch to create a pulmonary venous drainage route while preserving the cavoatrial junction. The postoperative course was uneventful. The patient was in good health, without arrhythmia and thromboembolism, 3 years after the operation.
