Mitral valve repair for congenital mitral valve stenosis in the pediatric population

摘要: Background Mitral valve repair is the preferred approach for congenital mitral stenosis in children. However, repairs this population remain challenging. Methods From 2001 to 2009, was attempted 20 consecutive patients. The median age and body weight at operation were 1.4 ± 1.9 years 7.4 4.1 kg, respectively. Multiple level left-side heart obstruction present 14 patients (70%).
