    Abstract:
    Two cases of 7 and 23 year of age with congenital aortic stenosis associated with the small valve annulus underwent successful aortic root replacement with pulmonary autograft (Ross procedure). Preoperative pressure gradient and the valve size were 120 and 80 mmHg, and 16 and 18 mm, respectively. Even with the small native aortic annulus, pulmonary autografts could be implanted to aortic annulus without autograft distortion by the method of total aortic replacement. The right ventricular outflow reconstruction was performed with PTFE-valved bovine pericardial conduit with securing the posterior muscular edge by a strip of autologous aortic wall. Postoperative course in both patients was uneventful without any rhythm disturbances. During the 12 and 14 months of follow-up, both patients were in excellent clinical condition with no evidence of autograft valve regurgitation and functional deterioration of valved conduit. This procedure was thought to be a preferable method of young cases with congenital aortic stenosis.
