摘要 目的:通过超声心动图评价继发性三尖瓣关闭不全患者行三尖瓣硬质三维环成形术的意义及疗效。方法:左心瓣膜手术同期行三尖瓣硬质三维环成形术的患者(TVP+组)35例,于术前、术后2周、术后1年通过超声心动图测量三尖瓣环直径(TVAD)、舒张期三尖瓣口E峰值流速(VE)、三尖瓣反流束面积(TRA)、三尖瓣反流分数(TRF)、右房内径(RAD)、右室内径(RVD)及右室射血分数(RVEF),重点比较术后与术前、术后1年与术后2周时各参数的变化。结果:与术前相比,术后2周及术后1年TVAD、TRA、TRF、RAD及RVD均显著减低(P<0.05),VE及RVEF无显著变化(P>0.05);术后1年与术后2周相比,TVAD、TRA、TRF无明显变化(P>0.05),而RAD及RVD进一步缩小(P<0.05)。结论:继发性中度以上三尖瓣关闭不全的患者应于左心瓣膜手术同期尽早行三尖瓣成形术,三尖瓣硬质三维环成形术有助于患者右心结构和功能的改善,且术后疗效稳定。
