Leadless pacemaker implant in patients requiring CIED extraction: outcomes based upon timing of extraction

Abstract Background Previous results from global Micra Transcatheter Pacemaker clinical trials have demonstrated leadless pacing as a safe and attractive option for patients with prior cardiac implantable electronic device (CIED) infection and extraction. Whether outcomes differ based upon the timing of prior device extraction has not been studied. Purpose To describe characteristics and outcomes of patients undergoing CIED extraction during or prior to Micra implantation. Methods Patients who underwent CIED explant and Micra implantation were identified from the Micra Post-Approval Registry and Micra Acute Performance studies. Baseline characteristics were summarized. A Fine-Gray competing…
