科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗器械医疗器械

背景情况:

使用自我膨胀 (SE) 门进行跨导管大动脉置换 (TAVR) 与需要永久起器 (PPM) 植入的导电干扰有关.
尽量减少PPM植入对于改善TAVR结果至关重要.

研究的目的:

为了比较顶重叠技术和传统的三顶共平面植入技术之间的新PPM植入率,用于TAVR与SE门.
评估与PPM植入和心脏阻塞有关的住院和30天的结果.

主要方法:

一项回顾性研究比较了519名接受TAVR与SE Evolut R或PRO门使用尖端重叠技术的患者 (2018年7月至2020年9月) 与128名接受TAVR标准三尖端技术的患者 (2016年4月至2017年3月).
分析了基线特征,住院和30天结果的数据,包括新的完整心脏阻塞和PPM植入.

主要成果:

与标准技术相比, cusp-overlap 技术组的医院内完全心脏阻塞率 (9.4%与23.4%) 和 PPM 植入率 (8%与21%) 显著降低.
在30天后,这些显著的减少仍然存在,在尖端重叠组中,完全心脏阻塞率 (11%vs. 23%) 和PPM植入率 (10%vs. 21%) 较低.
在住院和30天的随访中,这两种技术之间的新左捆分支块 (LBBB) 的发生率相似.

结论:

与标准三技术相比,SE Evolut门的TAVR顶重叠方法与永久心脏起器植入率显著降低.
这种技术在减少导电干扰和TAVR后需要PPM植入方面具有潜在的优势.
