[Modified warden procedure for partial anomalous pulmonary venous connection in an adult].

A 46-year-old woman was admitted to our hospital because of congestive heart failure and atrial fibrillation. She had undergone atrial septal defect repair at the age of 7 years. Computed tomography( CT)scan revealed right upper pulmonary vein returned to superior vena cave and the left upper pulmonary vein returned to the innominate vein. Cardiac catheterization showed Qp/Qs of 2.6. Pulmonary venous drainage repair and right-sided maze procedure was planned. The right upper pulmonary vein was led to the left atrium using the modified Warden Procedure. The left upper pulmonary vein was divided and anastomosed to the left atrial appendage. Concomitantly right-sided maze procedure was performed. Postoperative course was uneventful and CT scan revealed no stenosis at anastomotic sites. Sinus rhythm was retained and she was discharged on postoperative day 30.
