科学领域:
- 干预心脏病学 干预心脏病学
- 心脏电生理学 心脏电生理学
- 医疗器械技术 医疗器械技术
背景情况:
- 心房动需要治疗,例如左心房尾闭塞 (LAAO).
- 截面穿刺 (TSP) 是LAAO手术中的关键步骤,需要精确进入左心房.
- 传统的TSP技术带有风险,并可能影响程序效率.
研究的目的:
- 为了比较一种新型血管造形导线辅助TSP技术的疗效和安全性,与传统的布罗肯布罗针方法进行比较.
- 评估LAAO手术中一次性成功率,手术时间和并发症率的改善.
主要方法:
- 一个前性的,多中心的,随机对照试验 (ADVANCE-LAAO) 涉及心房的患者接受LAAO.
- 患者被随机分为两组:血管塑性导线辅助TSP (n=131) 和传统TSP (n=132).
- 主要终点是TSP的一次性成功率,次要分析包括手术时间,并发症率和同轴方向.
主要成果:
