Leadless cardiac pacemakers may be safely retrieved after several years

Reuters Health - 08/09/2020 - Leadless pacemaker (LP) retrieval was feasible and safe for 85% of patients in a single-center study of devices implanted for a mean of four years. As reported in JACC: Clinical Electrophysiology, Dr. Petr Neuzil of Na Homolce Hospital in Prague and colleagues retrieved implanted Nanostim LPs from 34 patients (mean age, 78; 63% men) whose devices were implanted in 2012-2014. The primary indication for retrieval was battery failure (85%), followed by device upgrade (12%) and elevation in pacing threshold (3%). The cohort was divided into two groups, based on fluoroscopic imaging: those with and without remarkable swinging movement (SM) of the LP docking button (25 vs. nine, respectively). The LP retrieval success rate was 85% overall. The success rate was significantly higher in the SM than in the no-SM group (100% vs. 44%), and the mean fluoroscopy time during the retrieval procedure was shorter in the SM group (12.7 min vs. 45.6...
