运用2-DE观察评价了36例直视和闭式扩瓣术近期效果,结果表明,术前2-DE测值与术中实测二尖瓣口大小十分相近,术后MVOD、MVOA、LAD、LVD和RVD等5项指标平均改善10～64％;但直视和闭式术后近期上述指标无甚差别。作者认为,MVOD、MVOA和LAD可做为了解二尖瓣扩瓣术疗效的定量随访指标。 The 2-DE observation was used to evaluate the short-term results of 36 cases of open-ended and expanded valvuloplasty. The results showed that the 2-DE before operation and the intraoperative measured mitral valve size were very similar, postoperative MVOD, MVOA, LAD, Five indicators such as LVD and RVD improved 10-64% on average; however, there was no significant difference between the above indexes in the immediate and immediate postoperative procedures. The authors believe that MVOD, MVOA and LAD can be used as a quantitative follow-up to understand the effect of mitral valve valvuloplasty.
