概括
隔膜膜切除术与外科动脉置换 (SAVR) 结合,即使在老年患者中,也能有效治疗严重的动脉狭窄 (sAS) 与左心室外流通道阻塞 (LVOTO). 这种手术改善了心脏功能,并提供了可比的生存率.
科学领域:
- 心血管外科心血管外科
- 心脏外科手术 心脏外科手术
- 心脏病学 心脏病学
背景情况:
- 七面肌切除术改善了高性心肌病的存活率.
- 肌切除术在严重的大动脉狭窄 (sAS) 与左心室外流通道阻塞 (LVOTO) 中的作用需要进一步调查.
- 确定通过肌切除术进行手术大动脉置换 (SAVR) 的最佳候选人至关重要,特别是随着跨导管大动脉置换的兴起.
研究的目的:
- 为了调查与SAS和LVOTO患者的SAVR同时进行的隔膜肌切除术的结果.
- 为了确定患者的特征和程序细节与成功的肌切除术在这个队列中相关.
- 评估SAVR的安全性,疗效和长期预后.
主要方法:
- 在2012年至2019年期间,对740名接受SAVR治疗sAS的患者进行了回顾性分析.
- 与并发肌切除术患者和没有并发肌切除术患者之间的人口和心声数据的比较.
- 对肌肉切除组的详细评估,包括诱导因素,手术细节,心声学变化和生存结果.
- 切除的隔膜组织的组织病理学分析.
主要成果:
- 肌肉切除组主要由老年女性组成,她们心脏小而超收缩.
- 带有肌切除术的SAVR导致左心室缩和LVOTO参数的显著改善.
- 肌肉切除组的生存率与之前的报告相似,包括75岁及以上的患者.
- 组织病理学揭示了切除的隔膜组织中的轻微纤维化.
结论:
- 与SAVR同时进行肌切除术是用LVOTO对sAS的安全有效治疗方法,即使在老年人群中也是如此.
- 该程序显著减轻了LVOTO,并改善了心脏结构.
- 患有严重AS的老年女性和小的,过度缩的,超收缩的心脏需要仔细的LVOTO评估;由于直接可视化和干预,肌切除术的SAVR可能会提供更好的好处.
- 带有肌切除术的SAVR为选定的患者提供了一种潜在的更有益的方法,尽管它具有侵入性.
