Key result
Leadless pacemaker implantation and early retrieval was feasible in 7 pediatric patients weighing 19 to 58 kg, with one perioperative pericardial effusion observed.
Why the study?
In pediatric populations, conventional transvenous and epicardial pacemaker systems carry complications including lead distortion from growth or activity, alongside lead and pocket complications.
Is leadless pacemaker implantation via internal jugular or femoral vein feasible and safe in pediatric patients?
Observational (n=7)
No
Is leadless pacemaker implantation via internal jugular or femoral vein feasible and safe in pediatric patients?
Leadless pacemaker implantation and early retrieval using internal jugular or femoral vein approaches is feasible in pediatric patients weighing as little as 19 kg.
May extend options to small children; hypothesis-generating and requires prospective validation.
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.
