Abstract:
Objective To summarize the experiences and long-term follow-up results in the treatment of severe mitral stenosis by balloon expansion in one step. Methods A new one-step method for direct mitral balloon expansion of the mitral valve was performed in 492 patients with mitral stenosis. Their mean age was 41.2?10.5y (15-68 y). 156 patients were male, and 336 were female. Results PBMV was effectively performed in 492 cases,and the success rate was 98.2% (483/492);mitral valve area was enlarged from 0.89?0.18cm 2 to 2.21?0.41cm 2 . 211 cases were followed-up from 8 months to 98 months. Restenosis rate for the dilated mitral valve was 11.4% (24/211),death rate 4.2%(9/211),and mitral valve replacement was done in 5.2% (11/211). Mean operation time was 36.5?12.1min. Conclusion Percutaneous mitral commissurotomy by balloon dilatation gave excellent immediate and late clinical results.
