PO-02-053 CHRONIC RETRIEVAL OF NANOSTIM ™ LEADLESS PACEMAKER (LP) FOR RIGHT VENTRICULAR PACING

Leadless cardiac pacemakers (LCPs) are an effective and safe alternative to transvenous for single-chamber ventricular pacing. Feasibility of retrieving replacing long-term implanted LCPs is not well established. We report a small single center series chronically Nanostim LCP™ leadless pacemakers. Since 2012 there were 103 devices successfully the right ventricle (RV) position. In 45 patients (M 26/ F 19), Ø age 72,5± 17 years, with average time since LCP implant 15470 ± 479 days retrieval procedure was indicated. The main indication extraction battery depletion indicative chemistry issue. Under fluoroscopy we observe movement location LCP. Single snare (42) or triple (3) catheter introduced through femoral venous puncture. With deflection docking bottom apply counter-clockwise rotation release from tissue insertion.Besides guided intracardiac echocardiography (ICE). successful in 39 out (86,6%).
