Sinus venosus atrial septal defect device closure

Abstract

With technical advancements, transcatheter closure of sinus venosus atrial septal defect (SVASD) proves safe and effective, even in developing countries. A 38-year-old male with recurrent palpitations underwent transesophageal echocardiography and cardiac computerized tomography, confirming a 14 mm SVASD with left-to-right shunt. Under GA and mechanical ventilation, we deployed a 19–25 mm ZYPHER-covered peripheral stent using 22 mm × 60 mm Z-Med II Balloon guidance. An angiogram confirmed adequate defect coverage. Postprocedure, occasional ventricular premature contractions and intermittent atrioventricular block were noted on 72-h Holter. Follow-up showed symptom resolution, with transthoracic echocardiography confirming stent placement and no residual shunt, endorsing device closure as a viable alternative to surgery.
