经皮球囊二尖瓣成形术远期疗效及再狭窄

The long term effects and restenosis in percutaneous mitral ballon valvuloplasty

目的：旨在研究本院３５０例经皮球囊二尖瓣成形术的远期疗效及再狭窄。 方法：采用改良的Ｉｎｏｕｅ 方法。 结果：经皮球囊二尖瓣成形术即刻成功率为９８．３％ （３４４／３５０），术后二尖瓣面积明显增加，为（１．１１±０．２９）～（２．１９±０．４０）ｃｍ ２ 。１０５例随访９个月～８ 年６ 个月，二尖瓣再狭窄率为１１．４％ （１２／１０５），死亡率为２．９％ （３／１０５），二尖瓣置换术为３．８％ （４／１０５）。 结论：研究提示，经皮球囊二尖瓣成形术近、远期疗效均很好。

Objectives: This study is to introduce of the clinical experience of percutaneous mitral balloon valvuloplasty 350 cases in Chinese and the long term follow up. Methods: The modfied Inoue method was performed. Results: Effective PBMV was performed in 344 cases, the success rate was 98.3%:mitral area assessed by 2 dimenrional echocardiography (1.11±0.29) to (2.19±0.40)cm 2, P <0.01 . One hundrad and five patients were followed at a mean (46.7±26.3) months (range 9 months to 8.5 years). after procedure restenosis was 11.4%(12/105), death 2.9%(3/105), cerebral embolism in 2, congestive heart failure in 1; mitral valve replacement in 3.8%(4/105). Conclusions:Percutaneous mitral commissurotomy provided excellent immediate and lale clinical results.
