Overview

May reduce collateral injury versus thermal ablation in AF; leaves open need for RCTs on durability and outcomes.

Key Points

  • This review evaluates pulsed-field ablation in comparison with conventional thermal ablation methods for atrial fibrillation treatment.
  • Narrative review of recent clinical trials, registries, and meta-analyses published in the last 5 years.
  • Included studies focused on clinical outcomes, procedural safety, and workflow metrics for atrial fibrillation management.
  • Qualitative synthesis comparing pulsed-field ablation with radiofrequency and cryoballoon ablation.
  • Pulsed-field ablation shows non-inferiority to thermal methods in achieving acute pulmonary vein isolation success.
  • PFA has lower incidence of esophageal injury and phrenic nerve dysfunction compared to thermal ablation.
  • Procedure and fluoroscopy times are shorter for PFA, along with a potentially lower anesthetic requirement.

Population

I
Intervention
Pulsed-field ablation (PFA)
C
Comparator
Conventional thermal ablation (radiofrequency and cryoballoon ablation)
O
Outcome
Acute PVI success, one-year freedom from arrhythmia, procedural safety, and workflow metrics

Pulsed-field ablation offers comparable efficacy to thermal ablation for atrial fibrillation with improved procedural efficiency and a potentially better safety profile regarding collateral tissue damage.

Limitations

  • Long-term durability data are still evolving
  • Evidence in persistent AF and complex substrate modification remains limited and varies across PFA platforms
  • Further randomised studies are required before its role in complex AF ablation strategies and guideline recommendations can be fully defined
  • Evidence in persistent AF and complex substrate modification remains limited
  • Evidence varies across PFA platforms
  • Further randomised studies are required

Cite This Study

Sikandar et al. (2026) conducted a review in Atrial fibrillation. Pulsed-field ablation (PFA) vs. Thermal ablation (radiofrequency and cryoballoon ablation) was evaluated. Pulsed-field ablation demonstrates non-inferiority to thermal ablation in achieving acute pulmonary vein isolation success and comparable one-year freedom from arrhythmia.
