对心房动 (AF) 的脉冲场移除 (PFA) 系统显示出不同的结果. 与循环导管系统 (LCS) 相比,Pentaspline导管系统 (PCS) 显示了较短的手术时间和较少的心肌损伤.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 医疗器械 医疗器械
背景情况:
- 脉冲场移除 (PFA) 系统正在出现,用于心房动 (AF) 的导管移除 (CA).
- 关于程序效率,低压区域 (LVA) 和心肌损伤的不同PFA系统进行比较的现实数据有限.
研究的目的:
- 为了比较两种商业可用的PFA系统的手术性能,急性腹LVA的程度和心肌损伤:Pentaspline导管系统 (PCS) 和循环导管系统 (LCS).
主要方法:
- 总共有120名患者接受了AF的de novo肺静脉隔离 (PVI).
- 使用PCS (n=90) 或LCS (n=30) 进行PFA.
- 通过3D电解剖绘图来评估急性腹LVA,并通过高灵敏度心肌损伤评估术后的心脏托洛T (hs-cTnT) 水平来评估心肌损伤.
主要成果:
- 所有患者都获得了急性PVI.
- 与LCS组相比,PCS组的总手术持续时间,左心房停留时间和除持续时间显著缩短.
- 与LCS相比,PCS与明显较小的急性腹LVA和较低的hs-cTnT水平相关,这表明心肌损伤较少.
结论:
- 在评估的PFA系统之间存在显著差异.
- 与AF切除中的LCS相比,PCS在程序效率和心肌损伤减少方面具有优势.
- 进一步的研究可能会探索不同PFA技术的长期结果和最佳利用.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...
