Surgery for Aortic Stenosis in Children: A 40-Year Experience

Background. Aortic stenosis (AS) is encountered in approximately 5 % of children with heart disease. The indications for surgery and the surgical techniques for AS are well established. This report focuses on the early and long-term outcomes in children with AS over a 40-year period. Methods. Included in this study were 508 patients ranging in ages from 1 day to 19 years, who were operated on for AS between 1960 and 2002. Eighty-one percent (414 of 508) of the patients had left ventricular outflow tract obstruction (LVOTO) at a single level: 40 supravalvar, 242 valvar (critical AS in 85 neonates and young infants and in 157 older children), and 132 subval-var. Nineteen percent (94 of 508) of the patients had LVOTO at more than one level. Associated congenita
