Leadless pacemaker patients following cardiac valve intervention in a long-term follow-up

Introduction Leadless pacemakers (LPM) have demonstrated adequate electrical performance and safety in patients with multiple commorbidities such as heart valve replacements at short-term follow-up. Purpose We present our experience in patients with LPM and heart valve replacements at long-term follow-up. Methods This was a prospective observational study including all consecutive LPM implantation from June 1 2005 to March 15 2021. Clinical, electrical, echocardiographic characteristics, related complications and electrical parameters were compared in 2 different groups with and with-out valve surgical procedure. Results A total of 255 LPM were implanted. Clinical, electrical and echocardiographic characteristics are described in table 1. Mean follow-up was of 24 months. There were no significant differences in electrical performance or related complications in between both groups (Figure 1). Conclusions Electrical performance and complications were no significantly different between both groups with and without heart valve replacements.
