Abstract Funding Acknowledgements Type of funding sources: None. Introduction Leadless pacemakers (LPM) have demonstrated safety in patients with multiple commorbidities. Very elderly patients have multiple commorbidities and are more prone to develop complications in pacemaker implants. Purpose We present our experience with LPM in a subgroup of very elderly patients. Methods We present a prospective clinical trial that including all consecutive LPM implantation from June 1 2015 to December 25 2021. We divide the patients in two groups according to age: older or younger than 85 y/o. Clinical and electrical, characteristics, as well as related complications and electrical parameters were compared between the two groups according to age. Results A total of 300 LPM were implanted and divided in two groups: 231 patients of less than 85 y/o and 69 patients ≥85 y/o. Clinical and electrical characteristics were described in table 1. Mean follow-up was of 36 months. There were 7 complications, all during the implantation procedure and there were no significant differences in complications between both groups . Electrical performance had no differences between the patients and was stable at long-term follow-up. (Figure 2) Conclusions There were no significant differences in complications or electrical performance between both groups and LPM were safe at long-term follow-up in very elderly patients with multiple commorbidities.
