再次PBMV35例疗效观察

目的　观察再次经皮二尖瓣球囊成形术 (PBMV)后患者疗效。方法　对 35例 PBMV后再狭窄的患者施行再次 PBMV,并与同期首次接受 PBMV的 36例患者进行疗效比较。结果　两组 PBMV均获成功 ,术后二尖瓣口面积 (MVA)增加 (P<0 .0 1) ,左房平均压 (L AMP)下降 (P<0 .0 1) ,肺动脉平均压 (PAMP)、左房舒张末内径 (L AD)明显降低 (P<0 .0 5 )。再次 PBMV组 MVA增加值及 PAMP下降值均小于首次 PBMV组 (P<0 .0 5 ) ,但 L AMP、L AP无统计学差异。两组均无严重并发症发生。结论　再次 PBMV是 PBMV术后再狭窄患者安全有效的治疗手段

Therapeatic observation of 35 patients with mitral restenosis underwent repeat percutaneows ballor mitral valvuloplasty

Objective To observe the result of patients with mitral restenosis underwent repent PBMV.Methods 35 patients with mitral restenosis following a successful first percutaneous ballon mitral valvuloplasty(PBMV) underwent repeat PBMV,and were compared with 36 randomly picked homochronous patients who received PBMV as an initial one.Results PBMV was successful in all the patients,producing an increase in mitral valve area(MVA)(P<0.01), a decline in mean left atrial pressure (LAMP) (P<0.01),and a notable reduction in both mean pulmonary arterial pressure (PAMP) and left atrial diameter (LAD) (P<0.05).The mean increment in MVA and reduction in PAP in patients after repeat PBMV were both less than those in whom PBMV was an initial procedure (P<0.05),but there was no statistical difference in the reduction of LAMP or LAD.There was on seious complication in either group.Conclusion Repeat PBMV is still a safe and effective therapeutic measure for patients with restenosis after initial PBMV.
