We experienced a rare form of PAPVD without atrial septal defect. The patient was a 33-year-old male and he was referred to our institute because of mild right pulmonary congestion detected by a routine chest X-P. Enlarged coronary sinus, right atrium and right ventricle were documented by UCG. The Qp/Qs was 1.9 and pulmonary artery pressure was 38/7 mmHg (mean: 17 mmHg) by cardiac catheterization. Selective pulmonary angiogram showed that all right pulmonary veins drained into the coronary sinus without evidence of an atrial septal defect. Enhanced chest CT clearly demonstrated the connection between the right pulmonary vein and the coronary sinus. Intracardiac repair without atrial baffle was carried out under hypothermic cardiopulmonary bypass. Under cardiac arrest with cardioplegia, the common wall between the right pulmonary vein and the left atrium was incised and the connection between the right pulmonary vein and the left atrium was established. The flap made by this incision was brought posterior to close the right pulmonary vein opening to the coronary sinus. The postoperative course was uneventful and the minimum diameter of the right pulmonary vein was found to be 15.5 mm by a postoperative pulmonary artery angiogram. This operative method without an atrial baffle could be an alternative procedure for coronary sinus type PAPVD.
