E-mail address: firstname.lastname@example.org An 84-year old man was admitted with presyncope due to battery failure of a TM leadless pacemaker (Nanostim St. Jude Medical) which had been implanted for bradyarrhythmias in 2014. Based on the presence of an occlusion in the sub- TM clavian vein and the patient’s preferences a leadless pacemaker (Micra Medtronic) was chosen as replacement. As the patient had concerns about complications from an extraction procedure the replacement device was im- planted without extraction of the dysfunctional leadless pacemaker. Access was through the femoral vein using a 23-French introducer. The device was placed at the mid-septum of the right ventricle sufficiently distant from the previous de- vice to avoid mechanical device interaction. A pull-and-hold fixation test was performed under fluoroscopy, depicted in the figure in RAO (Figure A) and LAO (Figure B) views (abandoned device indicated by arrows), to ensure the leadless pacemaker was securely embedded in the myocardium. Excellent electrical par- ameters, and unaffected papillary muscles and tricuspid valve function were con- firmed at the time of implant and at 3 months follow-up. This represents the first published implantation of a leadless pacemaker in a human patient with an abandoned leadless device. The procedure presents an alternative to current options when battery depletion or failure occurs in leadless pacemakers.
