title: [Valvuloplasties for acquired mitral insufficiency in children (Carpentier's technic). Long-term results in 87 cases].
abstract: Between March, 1969 and March, 1984, 89 children aged from 2 to 12 years (mean: 8.3 +/- 2.5 years) and presenting with mitral valve regurgitation underwent valvuloplasty by the Carpentier technique. The cause of the regurgitation was rheumatic fever in 84 cases (94 p. 100), bacterial endocarditis in 4 cases and Barlow's disease in 1 case. Mitral valve regurgitation was divided into 3 types, namely: type I, normal valve motion (5 cases), type II, valve prolapse (74 cases) and type III, restricted valve motion due to fibrosis of the leaflets or chordae (20 cases). The hospital mortality rate was 2.3 p. 100 (2 deaths). The cumulative follow-up was 546 patients/years, and the actuarial survival rate at 10 years was 89.96 +/- 8.5 p. 100. At 10 years the actuarial thromboembolic complication rate was 2 p. 100, or 0.3 +/- 0.2 p. 100 per patient year, and the actuarial valvuloplasty deterioration rate was 27 +/- 8.5 p. 100. The risk of re-operation was 2.2 +/- 0.6 p. 100 per patient year. At 10 years 78.4 +/- 7.2 p. 100 of the children were free of all re-operation, and 69 p. 100 had no complication. Thus, whenever possible (i.e. in 90 p. 100 of the cases, according to our experience) and considering the satisfactory long-term results, all children with acquired mitral valve regurgitation should undergo mitral valvuloplasty as first-line treatment.
