Window anastomosis technique for repair of supracardiac total anomalous pulmonary venous connection in infants

Outcomes of operations for total anomalous pulmonary venous connection (TAPVC) have improved.However, postoperative pulmonary venous obstruction (PVO) remains the most significant complication, with high morbidity and mortality. We introduce a window anastomosis technique for repair of supracardiac TAPVC in infants. The mainstay of the surgical technique is to resect the anterior wall of the pulmonary vein confluence(PVC) and part of the posterior wall of the left atrium to form a large and undistorted “window to window” anastomosis.
