Implant efficiency and clinical performance of Aveir™ VR and Micra™ VR leadless pacemaker: A multicenter comparative analysis of 67 patients

Introduction Leadless pacemaker (LP) is a novel pacemaker that has been proven to be effective and safe; however, the majority of LPs in previous reports were the Medtronic Micra™ VR LP. We aim to evaluate the implant efficiency and clinical performance of the Aveir™ VR LP compared to the Micra™ VR LP. Method We performed a retrospective analysis in two healthcare systems (Sparrow Hospital and Ascension Health System, Michigan) in patients implanted with LPs between January 1, 2018, and April 1, 2022. The parameters were collected at implantation, 3 months and 6 months. Results A total of 67 patients were included in the study. The Micra™ VR group had shorter time in the electrophysiology lab (41 ± 12 vs. 55 ± 11.5 min, p = .008) and shorter fluoroscopic time (6.5 ± 2.2 vs. 11.5 ± 4.5 min, p
