Pediatric Micra leadless pacemaker implantation via internal jugular and femoral veins: experience with 11 patients

In pediatrics, conventional transvenous and epicardial pacemaker systems carry complications, such as lead distortion due to growth and activity, in addition to lead and pocket complications. A retrospective review of pediatric leadless pacing at the University of Minnesota Masonic Children's Hospital (MN, USA) from 2018 through 2021 was performed. Diagnoses, rationale for pacing, demographics, pacing thresholds and longevity of devices were recorded. Twelve leadless pacemaker insertions and one removal were performed successfully in patients weighing 19-90 kg. Six patients had Micra implantation via the internal jugular vein without surgical cut-down. Up to 3 years of follow-up were noted, with median follow-up of 22 months. No late complications occurred. Leadless pacemaker implantation and early retrieval were feasible in pediatric patients.
