Backgroundthis study was performed to assess the results of aortic valve replacement in children with biological substitutes including homografts, pulmonary autografts (Ross procedure), and aortic valve reconstruction with autologous pericardium (Duran technique).Methodsbetween March 1992 and July 2009, 73 children with aortic valve disease (mean age, 11.8 ±2.7 years) underwent aortic valve replacement with biological substitutes including homografts, pulmonary autografts, and aortic valve reconstruction with autologous pericardium. Associated procedures were mitral valve repair in 32 and subaortic membrane resection in 3.Resultsearly mortality was 1.4% (1 patient). Median follow-up was 94 months. Sixty (83.3%) survivors had insignificant aortic regurgitation. Reoperation was required in 7 (9.6%) patients: for autograft dysfunction alone in 2, autograft failure and failed mitral valve repair in 2, autograft dysfunction with severe pulmonary homograft regurgitation in 1, severe homograft aortic valve regurgitation in 1, and right ventricular outflow tract obstruction in 1. There were 4 (5.4%) late deaths. Actuarial reoperation-free, event-free, and aortic valve dysfunction-free survival were 92.5% ±4%, 93.4% ±3.3 %, 94% ±2.9%, 86.2% ±4.3%, respectively, at 94 months.Conclusionsaortic valve replacement with biological substitutes is associated with acceptable hemodynamics and midterm results.
