Long-term results of percutaneous mitral commissurotomy were evaluated in 410 patients with mean age of 31 years (18 to 68 years). 48% of patients had mean thickened leaflets, 35% had calcified valves and 17% had flexible leaflets and subvalvular apparatus. Procedure was performed with a double balloon in 57% and with Inoue's balloon in 43% patients. A good immediate results was obtained in 77% of patients. A good result was defined as a mitral valve area > or = 1.5 cm2 without mitral regurgitation. Clinical follow-up concern 378 patients. The actuarial 5 years rate were 84% in our serie, without surgery or new percutaneous mitral commissurotomy and good functional results (NYHA class I or II) were 71%. Valvular anatomy, immediate results (mitral valve area), history of mitral commissurotomy, old patients, atrial fibrillation can influence strongly the results.
对410例平均年龄31岁（18至68岁）的患者进行了经皮二尖瓣交界切开术的长期结果评估。48%的患者二尖瓣叶平均增厚，35%的患者瓣膜钙化，17%的患者瓣叶及瓣下结构柔软。57%的患者采用双球囊法进行手术，43%的患者采用Inoue球囊法。77%的患者获得了良好的即刻效果。良好效果定义为二尖瓣瓣口面积≥1.5平方厘米且无二尖瓣反流。临床随访涉及378例患者。在我们的系列研究中，5年精算生存率为84%，未进行手术或再次经皮二尖瓣交界切开术，且功能良好（纽约心脏协会I级或II级）的比例为71%。瓣膜解剖结构、即刻效果（二尖瓣瓣口面积）、二尖瓣交界切开术史、老年患者、心房颤动会强烈影响结果。
