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

A 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), with the posterior wall of the RUPV typically connected to the left atrium. While surgery is usually recommended for SVASD, percutaneous technique may serve as an alternative to surgery in selected patients. Here, we report on the percutaneous closure of the defective posterior wall of the SVC using a covered stent, thereby closing the superior SVASD and redirecting the anomalous RUPV behind the stent into the left atrium.
