Key result
Leadless pacemakers cut major complications ~67% vs traditional pacemakers but increase cardiac perforation risk.
Why the study?
Leadless pacemakers avoid pocket- and lead-related complications, but their clinical effect compared with traditional pacemakers remains controversial.
Do leadless pacemakers reduce major complications compared to traditional pacemakers in patients requiring pacing?
Meta-Analysis
Do leadless pacemakers reduce major complications compared to traditional pacemakers in patients requiring pacing?
Relative Risk: 0.33 (95% CI 0.25–0.44)
p-value: p=<0.00001
Leadless pacemakers significantly decrease the risk of major complications compared to traditional pacemakers, but are associated with a higher risk of cardiac perforation or pericardial effusion.

Leadless pacemakers may lower major complications; extends observational data but leaves perforation risk and practice change open pending RCTs.
Cui et al. (2020) reported a meta-analysis. Leadless pacemakers vs. Traditional pacemakers was evaluated on major complications (risk ratio 0.33, 95% CI 0.25-0.44, p=<0.00001). Leadless pacemakers significantly decreased the risk of major complications compared with traditional pacemakers (RR 0.33; 95% CI 0.25-0.44; P<0.00001), but increased cardiac perforation risk.
