NEJM:经导管或外科主动脉瓣置换的五年结局研究

2020-02-29 andrew 网络

在严重的主动脉瓣狭窄和中级手术风险的患者中,经导管主动脉瓣置换术(TAVR)治疗的患者相较于主动脉瓣置换术治疗的患者,长期临床结局和生物修复瓣膜功能的数据很少。

在严重的主动脉瓣狭窄和中级手术风险的患者中,经导管主动脉瓣置换术(TAVR)治疗的患者相较于主动脉瓣置换术治疗的患者,长期临床结局和生物修复瓣膜功能的数据很少。基于此原因,作者探究了经TAVR术治疗的患者的5年生存效益。
 
作者在57个中心招募了2032例具有严重症状性主动脉瓣狭窄的中危患者。根据预期的经股或经胸入路将患者分层(分别为76.3%和23.7%),并随机分配接受TAVR或手术替代。随访了5年的临床,超声心动图和健康状况结果。主要终点死亡或者致残性卒中
 
在5年时,TAVR组和手术组之间因任何原因或致残性卒中的死亡发生率均无显着差异(分别为47.9%和43.4%;危险比为1.09;95%置信区间[CI], 0.95至1.25;P = 0.21)。二者的结果相似(分别为44.5%和42.0%;危险比为1.02;95%CI为0.87至1.20),但经导管主动脉瓣置换术比经胸腔镜手术后死亡或致残性中风的发生率高(59.3%对48.3%;危险比1.32;95%CI 1.02至1.71)。在5年时,TAVR组的患者至少有轻度的瓣周主动脉瓣关闭不全(33.3%对6.3%)。TAVR治疗后的重复住院比外科手术后更频繁(33.3%对25.2%),主动脉瓣再介入也较手术后更为频繁(3.2%对0.8%)。TAVR和手术在5年时的健康状况改善相似。
 
在具有中等手术风险的主动脉瓣狭窄患者中,TAVR后5年死亡或致残性卒中的发生率与经外科手术主动脉瓣置换相比无显着差异。
