[Surgery for the valvular disease in children].

We report the results and long-term follow up in 34 children (17 girls and 17 boys, aged 12 days to 13 years, average age 3.3 years, average body weight 11.7 kg) who underwent valvular surgery in the period between May 1989 and November 1996. Operative mortality was 11.8%. Actuarial survival curves (including hospital mortality) indicate a 68.6% survival rate at 5 years and that 64.7% of patients are free from reoperation at 5 years. For aortic regurgitation two patients applied aortic valvuloplasty and four applied aortic valve replacement. Nine children had aortic stenosis, three of them had balloon valvuloplasty, seven had valvotomy, two had aortic valve replacement. Ten patients were treated for mitral regurgitation. There were nine valvuloplasty and four mitral valve replacement including three times of reoperation. One membranous pulmonary atresia and seven pulmonary stenosis children had valvotomy. There were four cases of tricuspid disease. One had tricuspid valve stenosis with pulmonary stenosis, three had severe tricuspid regurgitation who applied tricuspid valve replacement. Mortality was high in the critical AS, severe MR and TVR groups. Patients who survived the surgery and had no complications showed satisfiable results.
