概括

重复手术大动脉置换 (redo-SAVR) 显示出比内透管大动脉置换 (ViV-TAVR) 更好的长期存活率,尽管最初的风险更高. 需要进一步的临床试验才能做出最佳的治疗决定.

科学领域:

心脏病学心脏病学
心脏外科手术心脏外科手术
生物医学工程生物医学工程

背景情况:

内透管大动脉替换 (ViV-TAVR) 提供了比重复手术大动脉替换 (redo-SAVR) 更好的外科安全性.
对于退化生物假体门的ViV-TAVR和重复SAVR进行比较的长期结果仍然不清楚.

研究的目的:

为了比较ViV-TAVR与 redo-SAVR的长期结果,在患有退化生物假体门的患者中.
评估两种再干预策略之间的生存率和主要不良事件的差异.

主要方法:

一个1: 1倾向性得分匹配的分析,对接受复原SAVR或ViV-TAVR的医疗保险受益者进行了退化的生物假体门 (2011-2020年).
排除患有内心炎的患者,同时进行心脏手术或同一住院重复干预的患者.
主要结局:5年生存率. 二级结局:主要心血管不良事件和主要门事件无生存率.

主要成果:

在匹配的队列中 (每组1256名患者),重复SAVR具有较高的重大心血管不良事件 (17.4%vs13.1%),但更好的无重大门事件存活率 (71vs43个月) 和5年存活率 (62.3%vs46.7%).
对重复SAVR的长期生存益处在查尔森并发症指数层 (低风险和中高风险) 中持续存在.
与ViV-TAVR患者相比,Redo-SAVR患者的年龄更小,患结血性心力衰竭的基线较小.

结论:

与ViV-TAVR相比,Redo-SAVR可能提供更高的长期存活率,尽管术后发病率增加.
临床试验数据对于指导退化生物假体门的重新干预决策至关重要,特别是在具有良好的预期寿命的患者中.
