摘　　要：目的探讨经皮二尖瓣球囊扩张术(PBMV)治疗非单纯性二尖瓣狭窄(MS)的效果。方法使用超声心动图检测65例单纯性MS,MS合并轻、中度二尖瓣关闭不全(MR)和MS合并轻、中度主动脉瓣关闭不全(AR),3组患者PBMV术前及术后复查时,左室射血分数(LVEF)值和心脏房、室内径大小变化。结果3组PBMV后复查LVEF值较术前明显增大(P<0.01);左室内径与术前比较差异有统计学意义(P<0.05);单纯性MS组和MS合并轻、中度AR组PBMV术后复查时左房内径比术前明显减小(P<0.05);MS合并轻、中度MR组PBMV术后左房内径与术前比较差异无统计学意义(P>0.05)。结论非单纯性MS患者PBMV术后心功能有明显好转。Objective To discuss the effect of pereutaneous balloon mitral valvuloplasty （PBMV）on non simple mitral stenosis （MS）. Methods Sixty-five patients with simple mitral stenosis and non-simple mitral stenosis （MS with mild-medium MR and MS with mild-medium AR）were examined on the variation of their cardiac function and size by ehocardiography before and after PBMV. Results The left ventricular ejection fraetion of three groups patients significantly increased（P〈0.01 ）, there is no significant difference about the internal diameter of left ventricule among three groups before PBMV and after PBMV （P〉0.05）. Internal diameter of left auricle between simple MS and MS with mild-medium AR significantly increased after PBMV（P〈0.05 ）. Internal diameter of left auricle did not dramatically changed after PBMV than before in group of MS with mild-medium MR （P〉 0.05）. Conclusion Cardiac function of non-simple MS had been significantly improved after PBMV.
