摘　　要：改良的二尖瓣记分除瓣膜动度、厚度、钙化及瓣下变化四项指标外，又特别增加了交界变化这项指标，每项指标依次记１～４分。本文分析了行经皮球囊二尖瓣扩张术（Ｐｅｒｃｕｔａｎｅｏｕｓｂａｌｌｏｏｎｍｉｔｒａｌｖａｌｖｕｌｏｐｌａｓｔｙ，ＰＢＭＶ）治疗的１００例病人术前的二尖瓣记分及术后交界裂开情况。结果提示，二尖瓣记分对ＰＢＭＶ术后交界裂开具有重要的预测价值，应用于术前的病例选择。瓣膜僵硬、明显增厚、双侧交界明显增厚、钙化且总记分＞１４分的病人不宜行ＰＢＭＶ治疗。Abstract Echocardiographic data were analyzed in 100 patients undergoing percutaneous balloon mitral valvuloplasty (PBMV). Before PBMV a modified two-dimensional echocardiographic score including variables of mitral valve mobility, thickness, calcification, subvalvular change and commissural change was used with scores ranking from one to four for each parameter. The result showed that the scores of leaflet mobility, leaflet thickness, commissural changes and the total mitral valve scores were much. higher in those patients without commissural split post PBMV than those with commissural split after PBMV. But the scores of leaflet calcification and subvalvular changes in the two groups were not different significantly. Thus, the modified mitral valve morphology score may be valuable in predicting a commissural split after PBMV, and may be used in selecting patients for PBMV. These patients who have rigid valve leaflets, marked thickening of leaflets, marked thickening and calcification of fusion commissures, with are high total mitral valve morphology score (> 14 points) are not suitable for PBMV.
