摘　　要：目的 :探讨心房颤动 (AF)的经皮二尖瓣球囊扩张术 (PBMV)患者的特点和即刻效果。方法 :回顾性收集 40 5例风湿性二尖瓣狭窄AF的PBMV病人的临床、心脏照片、超声心动图、血流动力学资料 ,与 44 7例正常窦性心律 (NSR)的PBMV病人进行比较。结果 :(1)与NSR组相比 ,AF组的年龄和术前心胸比 (HTR)较大 ,术前二尖瓣口面积 (MVA)较小 ,而且心功能Ⅲ Ⅳ级 ,既往二尖瓣分离术史 ,二尖瓣病变计分 >8,术前二尖瓣反流 (Ⅰ Ⅱ级 )的百分率明显增高。 (2 )AF组PBMV即刻效果良好率明显低于NSR组 ,术后MVA明显小于NSR组 ,而术后肺动脉平均压 (PAMP)、左房平均压 (LAMP)明显高于NSR组。结论 :AF的PBMV病人临床和二尖瓣形态学条件都相对较差 。Objective:To study the feature and immediate outcome of patients in atrial fibrillation(AF) undergoing percutaneous balloon mitral valvuloplasty(PBMV).Methods:The data of 405 patients with rheumatic mitral stenosis(MS)in AF who underwent PBMV were retrospectively collected and compared with those of 447 patients in normal sinus rhythm(NSR).Results:(1)Compared with NSR group,patients in AF group were older,had a larger pre PBMV heart thorax ratio(HTR) and a smaller pre PBMV mitral valve area(MVA),and presenred more frequently with New York Heart Association(NYHA)class Ⅲ/Ⅳ,echocardiographic score>8,pre PBMV mitral egurgitation(MR)and with history of prior commissurotomy.(2)Compared with NSR group,patients in AF group had a lower rate of good immediate outcome of PBMV,a smaller post PBMV MVA and a higher post PBMV pulmonary artery mean pressure(PAMP)and left atrial mean pressure(LAMP). Conclusions:Clinical and morphologic features of patients with rheumatic MS in AF are inferior,and immediate outcome after PBMV of them is inadequate.
