[Percutaneous mitral commissurotomy: how can it be made simpler and more efficacious?].

Le résumé fourni par la source

The authors report the results of a simplified method of percutaneous mitral dilatation from 936 procedures. This method introduced in our service since 1997 consists in progressively increasing diameters inflation of Inoué balloon, using echographic control and without any arterial procedure. Our population consists on 683 women (73%) and 253 men with a mean age 34 +/- 15 years (extremely 9 and 80 years) with subgroups composed of 26 pregnant women, 32 children less than 17 years, 59 restenosis after closed heart mitral commissurotomy, 14 restenosis after open heart mitral commissurotomy, 74 restenosis after percutaneous mitral commissurotomy, 5 tricuspid and mitral dilatation, 2 coronary and mitral dilatation (with stenting), 2 patients with a history of surgical mitral valvuloplasty for pure mitral regurgitation. The mitral area passed from 1 +/- 0.2 cm2 to 2.1 +/- 0.1 cm2. A surgical mitral regurgitation was observed in 3 cases. The time of fluoroscopy was 6.4 +/- 3.3 min. The hole time procedure was 19 +/- 9 min. The delay of hospitalisation was one day in 97% of patients. The decreased cost was about 20%. The patient comfort and the large diffusion of this method predicts a good future of this simplified technique.
