概括

这项研究介绍了一种新的心上导管切除技术,用于内心方法失败时的左侧辅助通路 (AP). 这种新型冠状动脉鼻方法在大多数患者中被证明是有效和安全的,为具有挑战性的病例提供了可行的替代方案.

科学领域:

心脏病学心脏病学
电力生理学电力生理学
医疗器械医疗器械

背景情况:

左侧辅助通路 (APs) 可能具有挑战性,使用常规内心技术进行切除.
以往使用射频能量或直流电击的废除尝试可能没有成功.

研究的目的:

描述一项用于左侧AP的新型心上导管切除技术.
评估通过冠状动脉鼻壁进行射频除的疗效和安全性.

主要方法:

采用单极射频能量应用,通过冠状动脉鼻腔壁准上心脏.
采用带有4毫米远端电极的可转向导管扫描冠状动脉鼻并识别心表AP插入.
调整了导管尖的偏移,以增强心室电图和心表接触.

主要成果:

在 8 名耐心内心切除的患者中,成功切除了 7 名左侧AP.
应用了射频能量 (20-30W10-60秒).
没有观察到严重的并发症,尽管发生过渡性疼痛;在射频应用期间的退出减轻了断裂风险.
随访显示,在7名患者中,AP导电的持续废除持续了1-10个月.

结论:

通过冠状动脉鼻进行心上导管切除是一种有效且相对安全的替代方案,用于当内心切除失败时的左侧AP.
这种技术为复杂的辅助路径案例提供了有希望的解决方案.

Tracheostomy Decannulation

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
