摘要
目的观察经皮二尖瓣球囊扩张术（ＰＢＭＶ）治疗风湿性心脏病（风心病）二尖瓣狭窄的中、远期疗效。方法采用Ｉｎｏｕｅ单球囊对６８０例风心病二尖瓣狭窄者行ＰＢＭＶ术治疗，其中３９４例进行了随访。平均随访时间（３６±１４）个月。结果二尖瓣平均跨瓣压差由（１８．２±６．８）ｍｍ Ｈｇ降至（７．２±３．８）ｍｍ Ｈｇ，瓣口面积由（１．０４±０．２１）ｃｍ２增至（１．９８±０．５５）ｃｍ２，左房内径由（４４±８）ｍｍ降至（３８±６）ｍｍ；８例出现明显再狭窄，其中５例再次ＰＢＭＶ术，３例行瓣膜置换术。结论随访结果证实，ＰＢＭＶ治疗风心病二尖瓣狭窄的中、远期效果良好，瓣膜条件特别是瓣下病变的程度是影响中、远期疗效的重要因素。
Objective To evaluate the long-term effect of mitral valve stenosis treated by percutaneous balloon mitral valvuloplasty (PBMV).Methods 680 cases of rheumatic mitral valve stenosis were treated by PBMV with Inoue single balloon. 394 cases were observed 38±14 months.Results Mitral valve dilatation resulted in a decrease in left atrail diameter from (44 ± 6)mm, a decline in transmittal valve pressure gradient from (18.2±6.8)mm Hg to (7.2 ± 3.8)mm Hg, and an increase in mitral valve area from (1.04±0.21)cm2 to (1.98±0.55)cm2. 8 cases of severe restenesis developed. Among them a second PBMV is required in 5 case, 3 cases received mitral replacement. Conclusion Follow-up data shows PBMV can achieve excellent long-term results. The condition of the valves especially the seventy of the subvavular lesion are the most important factors which affect the long-term effect.
