Adult Partial Anomalous Pulmonary Venous Return Repair and Superior Vena Cava Syndrome: A Delayed Complication of the Warden Procedure.

The Warden procedure is one of the most common techniques for surgical correction of partial anomalous pulmonary venous return (PAPVR), involving transection and reanastomosis of the superior vena cava (SVC) to the right atrial appendage and baffling of the anomalous pulmonary veins through the atrial septal defect. While the procedure is typically well-tolerated in pediatric patients, adult patients requiring surgical correction of PAPVR are uncommon. The authors report a case of a 33-year-old woman who developed SVC syndrome as a delayed complication of the Warden procedure. Cardiac, Congenital, Complications © RSNA, 2022.
