Authors' conclusion

Contemporary catheter ablation modalities demonstrated broadly comparable efficacy and safety for AF. PFA was associated with greater AF burden reduction and superior procedural efficiency, whereas the observed hospitalization benefit was not confirmed in Bayesian sensitivity analysis and warrants cautious interpretation.

Study context

Population
Patients undergoing catheter ablation for atrial fibrillation (AF)
Participants
7,226 patients · 32 randomized controlled trials
Comparison
Comparative effects across 5 ablation energy modalities

Pooled result

As reported in the abstract

Atrial tachyarrhythmia recurrence, repeat ablation, cardioversion, patient-reported outcomes
  • No significant differences were observed among modalities

Hospitalization

Bayesian sensitivity analysis showed no significant differences across modalities

Procedural efficiency

Both pulsed field ablation (PFA) and cryoballoon ablation (CBA) were associated with shorter total procedure duration and left atrial dwell time than RFA
fluoroscopy time was shortest with RFA
