Abstract

Between 1993 and 2000, 50 patients (age range, 1 month to 18 years) who had left ventricular outflow tract (LVOT) disease and had undergone a Ross procedure were assessed using echocardiography. Aortic annulus size, valvular gradient, valve insufficiency, LV dimensions at end-systole and end-diastole, LV interventricular septal and posterior wall thickness, and LV mass index (LVMI) were measured. There was 1 early and 2 late deaths, and 5 reoperations. Aortic annulus size increased and degree of aortic insufficiency (AI) decreased, as did LV internal dimensions and LVMI. Peak pressure gradients declined from 73 ± 18 mm Hg to 7 ± 7 mm Hg, and LVMI regressed (167 ± 6 g/m2 v 108 ± 6 g/m2, P < .001) after 3 years. The degree of AI ranged from none to mild, and no patient has LVOT stenosis. Regression of LV dilatation and hypertrophy, good autograft valve function and durability, and a high survival rate suggest that the Ross procedure is preferred for most children who require aortic valve replacement.
