Key result
PFA offers speed and tissue selectivity while thermal modalities maintain competitive cost and durability.
Why the study?
Thermal ablation modalities carry inherent risks of collateral thermal injury and lesion inconsistency, driving the search for alternative energy sources such as pulsed-field ablation.
Does pulsed-field ablation improve clinical efficacy, safety, and procedural implementation compared to thermal ablation modalities in patients with atrial fibrillation?
Does pulsed-field ablation improve clinical efficacy, safety, and procedural implementation compared to thermal ablation modalities in patients with atrial fibrillation?
While pulsed-field ablation offers advantages in procedural speed and tissue selectivity, established thermal modalities remain competitive regarding cost-effectiveness and long-term durability.

Does not warrant shifting from thermal modalities; leaves open randomized PFA durability and cost trials.
Martignani et al. (2026) studied this question. Pulsed-field ablation (PFA) offers advantages in speed and tissue selectivity, yet thermal modalities like cryoballoon maintain competitive cost-effectiveness and durability.
