Resumen

Partial anomalous pulmonary venous drainage is an uncommon condition representing 0.6% of all congenital malformations that may be associated with an atrial septal defect. In the present report, we describe a modification of the Warden technique for surgical repair of partial anomalous pulmonary venous drainage with atrial septal defect by using a superior vena cava flap and a right atrial appendage flap to create a new tension-free cavoatrial continuity (neo right superior vena cava), along with redirection of the anomalous pulmonary veins to the left atrium through the atrial septal defect using an autologous pericardial patch. The patient had a favorable postoperative course, with no evidence of residual shunt or obstructive gradient across the anastomosis, and was discharged on postoperative day six.
