title: Semilunar valve switch in aortic insufficiency.
abstract: The use of the Ross procedure in young patients is gaining wider acceptance. The need for a foreign pulmonary valve that will require replacement, however, is a serious drawback. To circumvent this problem, we reimplanted the native aortic valve in the pulmonary position in four patients (ages 12, 15, 15 and 17 years old) operated on utilizing the Ross procedure for aortic insufficiency. One patient had congenital and three isolated rheumatic aortic insufficiency. The root replacement technique with coronary artery reimplantation was used. All patients did well initially with marked reduction of left ventricular dilatation and good function of the reimplanted native aortic valve. One patient, however, died a month later from rupture of a false aneurysm that developed at the pulmonary autograft to ascending aorta anastomosis. We feel that the use of the native aortic valve in the pulmonary position makes the Ross procedure more attractive and potentially curative. The diseased aortic valve works well in the pulmonary position because of lower pulmonary artery pressure and resistance.
