- Feasibility and Safety of Left Bundle Branch Pacing in Nonagenarians: A Single Center Observational Study Hwan Juet Khaw Mohammad Paymard Pacing and Clinical Electrophysiology ABSTRACT Background Left bundle branch pacing (LBBP) is emerging as a physiological pacing strategy. However, data on its feasibility and safety in nonagenarians (≥90 years) with symptomatic bradycardia are limited. This study aims to evaluate the outcomes of LBBP in this frail, high‐risk population. Methods A retrospective analysis was conducted on 8 patients aged 90 and older who underwent LBBP between December 2023 and December 2024. Procedural outcomes, complications, and pacing parameters were assessed. Results LBBP was successfully performed in 8 patients (mean age 93 ± 2 years, mean Clinical Frailty Score 5). The pacing indications included atrioventricular block and sinus node dysfunction. The mean left ventricular activation time was 75 ± 8 ms. At a median follow‐up of 6 weeks, pacing parameters remained stable with no evidence of lead displacement, haematoma, or infection. There were no immediate procedural complications. Conclusions LBBP appears to be a feasible and safe physiological pacing strategy in nonagenarians with symptomatic bradycardia. Further studies are needed to confirm the long‐term outcomes of LBBP in elderly patients. 10.1111/pace.70189 http://onlinelibrary.wiley.com/termsAndConditions#vor
