摘　　要：前瞻性观察二尖瓣环大小及运动幅度对经皮二尖瓣球囊扩张术（ＰＢＭＶ）疗效的影响。结果：风心病二尖瓣狭窄组的二尖瓣环直径较正常对照组明显增大，瓣环在心动周期中的变化值、变化率及位移较正常对照组明显减少。风心病二尖瓣狭窄患者瓣膜超声评分＞８分组与≤８分组比较，瓣环较小，瓣环的变化值、变化率及位移明显降低。术后疗效满意组的二尖瓣环大小及运动幅度均大于非满意组。１９个相关因素多元逐步回归分析表明。Toobservetheinfluenceofmitralsizeandmotionrangeonresultofpercutaneousballoon mitral valvuloplasty.Mitralannulusdiameterislargerinexperimentgroupthanincontrolgroup,theabsolutechangeandthechangeratioofmitralannulussizeinthecardiccyclearesmallerinexperimentgroupthanincontrolgroup,mitralvalveannulusdisplacement(MVAP)isremarkablydecreasedinexperimentgroupcomparedwiththatincontrolgroupThemoreseriousofmitralvalveimpairment is,themoredecreased mitralannulussizeandmotionareThesizeandmotionofmitralannulusarenotablydecreasedinechocardiographicscore>8group,Compared with that in echocardiographic score8 group.mitralannulussizeandmotionaredecreased obviouslyinsuboptimalgroupthanthatin good groupMultiplestepwiseregressionanalysesshowthatmitralsizeandmotionsignificantlyaffecttheresultofPBMV
