This report describes the use of the Amplatzer patent ductus arteriosus occluder to close a left ventricle to descending aorta conduit. The patient was a 10-year-old male who was born with critical aortic stenosis and left ventricular outflow tract obstruction. After initial valvotomy, he underwent left ventricular to descending aorta conduit placement. At the age of 10, he had a Konno procedure to enlarge the left ventricular outflow tract and 21-mm St. Jude aortic valve placement. Closure of the conduit was not addressed because it was inaccessable from median sternotomy. Postoperatively, echocardiogram revealed significant flow through the conduit with a wide pulse pressure. Cardiac catheterization was performed with the premise to close the conduit with an Amplatzer patent ductus arteriosus occluder device.
