Permanent cardiac pacemakers have traditionally comprised a surgically implanted subcutaneous pulse generator affixed to at least one transvenous pacing lead. Despite technological advances, implant-related complications and transvenous-lead failure rates have remained high. The Micra Transcatheter Pacing System is a miniaturized single chamber pacemaker that is implanted directly into the right ventricle, eliminating the subcutaneous pocket and creating a leadless pacemaker system. Registry data show an extremely high implant success rate, significantly lower major complication rates than transvenous pacemakers, stable pacing parameters and reliable battery performance. In this review we summarize the available clinical literature and highlight the promising efficacy and safety of the Micra Transcatheter Pacing System.
传统上，永久性心脏起搏器由通过手术植入皮下的脉冲发生器和至少一根经静脉起搏导线组成。尽管技术不断进步，但与植入相关的并发症和经静脉导线故障率仍然很高。美敦力Micra无导线起搏器系统是一种小型化单腔起搏器，可直接植入右心室，无需皮下囊袋，从而形成一种无导线起搏器系统。注册数据显示，其植入成功率极高，主要并发症发生率明显低于经静脉起搏器，起搏参数稳定，电池性能可靠。在本综述中，我们总结了现有的临床文献，并强调了美敦力Micra无导线起搏器系统令人期待的疗效和安全性。
