The Micra transcatheter pacing system (Medtronic, Fridley, MN) has been implanted successfully in more than 2500 patients in clinical trials.1, 2 Data on retrievals of these devices have` been mainly limited to early retrievals. Afzal and colleagues3 reported on techniques of retrieval of 29 Micra devices. Eleven of those retrievals occurred during the implant procedure while 18 were removed a median of 46 days postimplantation (range, 1–95 days).3 Grubman and colleagues4 reported on 3 retrievals (9–406 days) postimplantation. Some autopsy reports have shown the potential for complete encapsulation of long-indwelling Micra devices.5, 6 This has raised some concerns over the extractability of longer-indwelling Micras. In this case we report on the extraction of a Micra pacemaker implanted 4 years prior.
