[Modified Warden Procedure for Correction of Partial Anomalous Pulmonary Venous Connection and Sinus Venosus Atrial Septal Defect in an Adult].

A 32-year-old woman was referred to our hospital for the surgical indication of sinus venosus-type atrial septal defect. Preoperative computed tomography scan revealed that the right upper pulmonary vein returned to the high superior vena cava. We performed a modified Warden procedure using a pedicle flap of the right atrial appendage along with a fresh autologous pericardium. Her postoperative course was uneventful with no venous obstruction or sinus node dysfunction. This technique is a useful surgical option for a partial anomalous pulmonary venous connection especially in adults.
