概括
与传统的CRT相比,干预心脏再同步治疗 (I-CRT) 提供了改善的左心室位和四极使用. 尽管冠状动脉鼻时间较长,但I-CRT并没有增加整体植入时间.
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:
- 干预心脏再同步治疗 (I-CRT) 是传统的CRT (T-CRT) 的辅助,用于左心室 (LVL) 的放置.
- 人们担心I-CRT耗时且复杂.
研究的目的:
- 为了比较I-CRT和T-CRT之间与手术相关的,术前,术后和临床结果.
- 评估I-CRT与T-CRT在LVL植入中的有效性和效率.
主要方法:
- 连续CRT心脏起器/除器患者的回顾性单中心队列研究 (2012年1月 - 2018年8月).
- 患者接受了T-CRT (2012年1月至2015年6月) 或I-CRT (2016年1月至2018年8月).
- 从患者记录,光学和国家心脏起器/ICD注册表收集的数据;使用适当的统计测试进行分析.
主要成果:
- 在I-CRT (82.7%) 与T-CRT (76.8%) (P=.015) 中,最佳的LVL位置更高.
- I-CRT使用四极LVL的频率更高 (99.0%与55.3%,P<.001) 和较少的线索 (0.7%与10.5%,P<.001).
- 总植入时间相似 (81.0分钟I-CRT vs 83.0分钟T-CRT,P=.41),但冠状动脉鼻停留时间较长I-CRT (45.0分钟vs 37.0分钟,P<.001).
结论:
- I-CRT不延长总植入时间,尽管冠状动脉鼻时间增加了.
- I-CRT促进了优越的LVL放置,更多地采用四极导线,并减少了导线使用.
- I-CRT为T-CRT提供了可行的替代方案,提供了改进的定位和设备特性.
