Key result
Pulsed field ablation shortens procedures by ~10 minutes vs cryoballoon ablation with noninferior arrhythmia recurrence.
Why the study?
Pulsed field ablation is a novel nonthermal ablation technique for AF, but a comparison of its procedural efficiency and safety profiles against cryoballoon ablation was needed.
Does pulsed field ablation improve procedural efficiency and safety compared to cryoballoon ablation in patients with atrial fibrillation?
Population
2875 patients with AF across 9 observational studies
Comparison
PFA (n = 1105) vs CBA (n = 1770)
Design
Systematic review and meta-analysis

Pulsed field ablation shortens procedures with noninferior arrhythmia recurrence; extends evidence supporting its efficiency over cryoballoon ablation.
Meta-Analysis (n=2,875)
Does pulsed field ablation improve procedural efficiency and safety compared to cryoballoon ablation in patients with atrial fibrillation?
Effect estimate: MD -10.49 (95% CI -15.50 to -5.49)
p-value: p=<0.0001
Pulsed field ablation shortens procedure time and reduces phrenic nerve palsy compared to cryoballoon ablation, but may increase the risk of cardiac tamponade, with similar rates of arrhythmia recurrence.
Wan et al. (2024) conducted a meta-analysis in Atrial fibrillation (n=2,875). Pulsed field ablation (PFA) vs. Cryoballoon ablation (CBA) was evaluated on Procedural duration (MD -10.49, 95% CI -15.50 to -5.49, p=<0.0001). Pulsed field ablation significantly shortened procedural duration compared with cryoballoon ablation (MD -10.49 minutes; P<0.0001) and demonstrated noninferiority for atrial arrhythmia recurrence.
