Key result
Leadless Micra pacemaker shows near-complete endothelialization just 4 months post-implant in a single case.
Why the study?
The degree of endothelialization of leadless pacemaker systems and implications for explantation strategies are not well described.
Case Report (n=1)
Leadless pacemakers can become nearly completely endothelialized within 4 months of implantation, suggesting that future extraction may require cardiac surgery.
No takes yet. Share an insight, caveat, or question.
May offer pacing alternative after epicardial leads in congenital disease; leaves open durability, infection prevention, and applicability in larger cohorts.
Borgquist et al. (2016) conducted a case report in Congenital heart disease with complete A-V block and recurrent device-related infections (n=1). Leadless pacemaker (Medtronic Micra) implantation was evaluated on Endothelialization of the leadless pacemaker in the explanted heart. In a 43-year-old man, a leadless Medtronic Micra pacemaker was found to be nearly completely endothelialized and embedded within the cardiac wall just 4 months after implantation.
