交界区病变对预测球囊扩张术后二尖瓣储备功能的意义

Implication of pathological changes in the commissure in predicting the mitral valve reserve function after percutaneous balloon mitral valvuloplasty

目的 探讨交界区病变对预测球囊扩张术后二尖瓣储备功能的意义。方法 本研究采用交界区钙化与否作为预测球囊扩张术后二尖瓣口储备功能的单独指标，并与Wilkins法作比较。结果 交界区钙化组球囊扩张术后其二尖瓣口面积较非钙化组小，其二尖瓣储备功能明显较交界区非钙化组差。结论 本研究进一步证明，交界区的病理改变能较好地预测二尖瓣球囊扩张（PBMV）的效果；检测交界区钙化与否方法简便，重复性好，是检测PBMV后二尖瓣储备功能的良好单独预测指标。

：Objective To decide whether commissure pathological changes are of value in predicting the reserve mitral function after percutaneous balloon mitral valvuloplasty (PBMV). Method The study adopted commissure calcification as a single index to predict the reserve mitral valve function after PBMV. Results Compared with Wilkins variables, the mitral valve area in commissure calcification group is less than that in non-calcification group. Moreover, the reserve mitral valve function of the calcification group is much worse than that of non-calcification group. Conclusion The pathologic changes in commissural area can predict the effect of PBMV. Commissural area calcification is a convenient single index with good reproducibility to predict the reserve mitral function after PBMV.
