Percutaneous Closure of a Superior Sinus Venosus Atrial Septal Defect as an Alternative to Surgical Treatment

Superior sinus venosus atrial septal defect (SVASD) results from a defect in the atrial wall that forms the posterior wall of the superior vena cava (SVC) and the anterior wall of the right upper pulmonary vein (RUPV). The posterior wall of the RUPV is usually connected to the left atrium. While surgery is usually recommended for SVASD, the percutaneous technique may be an alternative to surgery in selected patients with SVASD. We report percutaneous closure of the defective posterior wall of the SVC with a covered stent. This closed the superior SVASD and redirecting the anomalous RUPV behind the stent into the left atrium.
