Results Mitral valve dilatation resulted in a decrease in left atrail diameter from (44±6)mm, a decline in transmitral valve pressure gradient from (18.2±6.8)mm?Hg to (7.2±3.8)mm?Hg, and an increase in mitral valve area from (1.04±0.21)cm2 to (1.98±0.55)cm2. 8 cases of severe restenesis developed.

结果 二尖瓣平均跨瓣压差由(18.2±6.8)mm Hg降至(7.2±3.8)mm Hg，瓣口面积由(1.04±0.21)cm2增至(1.98±0.55)cm2，左房内径由(44±8)mm降至(38±6)mm；8例出现明显再狭窄，其中5例再次PBMV术，3例行瓣膜置换术。

Background— Mild commissural mitral regurgitation is associated with significantly higher restenosis-free surial after percutaneous mitral aluloplasty, which suggests that different mechanisms of significant MR after PM may hae different clinical courses.

背景 经皮二尖瓣成形术后轻度的联和部二尖瓣返流患者术后无再狭窄生存率明显较高，提示着成形术后不同机制的显著二尖瓣返流有不同的临床进程，因此对成形术后显著二尖瓣返流患者的长期预后因素进行了分析
