Pediatric Micra leadless pacemaker implantation via the internal jugular and femoral vein: a single-center, US experience.

Background

In the pediatric population, conventional transvenous and epicardial pacemaker systems carry complications such as lead distortion due to growth/activity, in addition to other lead/pocket complications. Materials & methods: A retrospective review of pediatric leadless pacing at the University of Minnesota Masonic Children's Hospital from 2018 to 2020 was performed. Rationale for pacing, demographics of patients, thresholds and longevity of devices were recorded.

Results

Seven leadless pacemaker insertions and one removal were performed successfully, in patients weighing between 19 kg and 58 kg. Three patients had Micra implantation via internal jugular vein. One pericardial effusion occurred perioperatively in a 19 kg patient with baseline thrombocytopenia, sideroblastic anemia and Pearson Marrow Pancreas syndrome.

Conclusion

Leadless pacemaker implantation/early retrieval is feasible in pediatric patients.
