超声评价二尖瓣狭窄经皮二尖瓣球囊扩张术后心功能变化

Change of cardiac function on non-simple mitral stenosis after PBMV by echocardiography,

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33例单纯性MS、MS合并轻、中度二尖瓣关闭不全(MR)和MS合并轻、中度主动脉关闭不全(AR)二组患者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术后复查时LVEF值较术前明显增大(P<0.001);左室内径与术前比较无显著差异(P<0.05);单纯性MS组和MS合并轻、巾度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无明显差异(P>0.05)。结论:非单纯性MS患者PBMV术后心功能也有明显好转。

Objective: To discuss the effect of percutaneous balloon mitral valvuloplasty (PBMV) on non-simple mitral stenosis (MS). Methods: Thirty-three 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 echocardiography before and after PBMV. Results: The left ventricular ejection fraction of three groups patients significantly increased (P<0. 001). 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.
