OBJECTIVE: To assess the short- and long-term efficacy of Inoue balloon percutaneous transvenous mitral commissurotomy (PTMC) with use of our simple balloon sizing method based on patient height. DESIGN: Data from 105 consecutive patients with symptomatic mitral stenosis who underwent 107 PTMC procedures between October 1991 and April 1995 at our hospital were analyzed. RESULTS: All PTMC procedures were successfully completed with no instances of cardiac perforation, systemic embolism, severe mitral regurgitation (grade 3 or more angiographically), or death. The mean mitral valve area increased from 0.8 +/- 0.2 cm2 to 1.7 +/- 0.4 cm2 (P = 0.0001), as assessed echocardiographically. Optimal results -- defined as an improvement in valve area of 50% or more or a final valve area of 1.5 cm2 or more without significant mitral regurgitation (an increase in mitral regurgitation of two or more grades or a final regurgitation of grade 3 or more) -- were obtained in 96% of patients. At a mean follow-up interval of 20 months, symptomatic benefit was maintained in 97% of patients. Echocardiographic evidence of restenosis (loss of more than 50% initial gain in valve area, a valve area of less than 1.5 cm2, or both) was noted in 9.8%. CONCLUSION: Inoue balloon PTMC with use of our simple balloon sizing method yielded excellent short- and long-term results in terms of mitral valve enlargement and sustained symptomatic benefit without the creation of severe mitral regurgitation. |
