Micra Extraction Out To 4.5 Years.

Leadless pacemaker systems (LPs) were developed as an alternative to traditional transvenous permanent pacemakers (TV-PPM) due to increasing rates of device and procedural related complications, leading to a high-cost burden to our health-care system. LPs were initially indicated for single-chamber ventricular pacing; however, recent developments have allowed for dual-chamber pacing too. These systems have demonstrated highly successful implant rates with stable pacing performance. This article describes the retrieval techniques of the Micra LPs and ways to mitigate challenges encountered during the retrieval process.
