Performance of the Micra cardiac pacemaker in nonagenarians

Abstract Introduction and objectives The Micra transcatheter pacing system has shown high effectiveness and a lower complication rate than conventional transvenous pacemakers. However, the benefit of the device is unknown in the very old population (≥ 90 years). The aim of this study was to evaluate the safety and effectiveness of Micra in patients ≥ 90 years. Methods We present a prospective observational study with consecutive patients aged > 70 years who underwent implantation of a Micra pacemaker system. Patients were divided into 2 groups: ≥ 90 and  Results The Micra system was implanted in 129 patients, of whom 41 were aged ≥ 90 years and 88  Conclusion The Micra leadless pacing system seems to be safe and effective in patients older than 90 years. It may be considered a reasonable alternative to conventional transvenous pacing in this population.
