The sedate uptake of pulsed field ablation (PFA) in Europe failed to presage the enthusiasm that drove the technology’s extraordinarily rapid adoption in the U.S. in 2024. Used to treat atrial fibrillation, PFA received its first U.S. FDA approval in Dec. 2023. At the time, Clarivate estimated that PFA had 7% of the global cardiac ablation market. By year-end 2024, it had 20% and Boston Scientific Corp. projected that PFA would represent up to half of the market by the close of 2025.
