Why the study?
Transvenous pacemakers carry significant complications, and data on leadless pacemakers in high-risk patients ineligible for transvenous systems remain limited.
Does leadless pacemaker implantation provide safe and effective pacing in high-risk bradyarrhythmia patients unsuitable for transvenous pacing?
Population
138 high-risk bradyarrhythmia patients unsuitable for transvenous pacing across four Israeli hospitals
Comparison
Leadless pacemaker implantation
Design
Retrospective observational multicenter registry
Follow-up
12 months
Key result
Leadless pacemaker implantation in high-risk patients achieved a 98% procedural success rate, with a 1-year cumulative complication rate of 4.7% and all-cause mortality of 12.3%.

Does leadless pacemaker implantation provide safe and effective pacing in high-risk bradyarrhythmia patients unsuitable for transvenous pacing?
Leadless pacemaker implantation is a safe and effective alternative with high procedural success and low complication rates in high-risk patients unsuitable for transvenous systems.
Katz et al. (2026) conducted an observational in High risk bradyarrhythmia unsuitable for transvenous pacing (n=138). Leadless pacemaker implantation was evaluated on Procedural success. Leadless pacemaker implantation in high-risk patients achieved a 98% procedural success rate, with a 1-year cumulative complication rate of 4.7% and all-cause mortality of 12.3%.
