- Results There were difference in the mitral valve area、diastolic mitral gradient、the mean left atrial pressure observed before and after PBMV. 结果显示PBMV前后二尖瓣瓣口面积、二尖瓣平均跨瓣压差、左房平均压力差异显著(P＜0.;05)；
- Results:PBMV was successful in all the patients of the two groups,producing an increase in mitral valve area(MVA)(P<0.01),a decline in mean left atrial pressur... 再次PBMV组二尖瓣瓣口面积增加值及肺动脉平均压下降值均小于首次PBMV组(P<0.;05);但左房平均压、左房舒张末内径下降值相比无统计学差异。两组均无严重并发症发生。结论:提示再次PBMV仍是PBMV术后再狭窄患者一种安全有效的治疗手段。
