Transcatheter Leadless Pacing in Children: A PACES Collaborative Study in the Real-World Setting
Authors' conclusion
Initial results from the Pediatric and Congenital Electrophysiology Society TLP registry demonstrated a high level of successful Micra device implants via femoral and internal venous jugular approaches with stable electrical parameters and infrequent major complications.
