A novel use of Amplatzer duct occluder

This report describes the use of the Amplatzer patent ductus arteriosus occ luder to close a left ventricle to descending aorta conduit. The patient wa s a 10-year-old male who was born with Critical aortic stenosis and left ve ntricular outflow tract obstruction. After initial valvotomy, he underwent left ventricular to descending aorta conduit placement. At the age of 10, h e had a Konno procedure to enlarge the left ventricular outflow tract and 2 1-mm St. Jude aortic valve placement. Closure of the conduit was not addres sed because it was inaccessable from median sternotomy, Postoperatively, ec hocardiogram revealed significant flow through the conduit with a wide puls e pressure. Cardiac catheterization was performed with the premise to close the conduit with an Amplatzer patent ductus arteriosus occluder device.
