Background The rate of pacemaker (PM) implantations is continuously growing. A large number of elderly patients is expected to be implanted in the future. We aimed at analyzing the short and long-term outcome after PM replacement in nonagenarians. Methods Patients aged ≥90 yo referred for PM replacement from January 2004 to July 2014 were retrospectively included. The primary clinical endpoint was total mortality. Results 62 patients were included (93.3±2.9yo at the time of PM replacement). During the follow-up, 37 patients (59.7%) died. Survival rates were 84.2% (95%CI:71.8-91.5%), 66.9% (95%CI:51.8-78.2%) and 22.7% (95%CI:10.6-37.7%) after 1, 2 and 5 years, respectively. Atrial fibrillation (OR 2.44, 95%CI:1.07-5.58) and non-physiological pacing, (OR 2.52, 95%CI:1.12-5.65) were independent predictors of mortality. Conclusion PM replacement in nonagenarians is a safe and straightforward procedure. Patients living for a median time of 30 months after the replacement.
