Key result
Pulsed field ablation demonstrates high efficiency and safety for PVI, expanding across complex arrhythmias.
Why the study?
Pulsed field ablation has rapidly emerged in catheter ablation, but current knowledge gaps, high heterogeneity across commercial systems, and the lack of standardized terminology, homogenous procedural endpoint definitions, and lesion durability assessment remain major challenges as technological innovations expand its clinical indications.
This review highlights how ongoing innovations in pulsed field ablation waveforms, purpose-built catheter architectures, and 3D electroanatomical mapping integration are expanding PFA applications beyond pulmonary vein isolation to complex atrial and ventricular arrhythmias, while emphasizing the critical need for standardized procedural endpoints and durability validation.
Pulsed field ablation (PFA) has rapidly emerged as a major development in catheter ablation, with increasing clinical adoption driven by procedural efficiency and a favorable safety profile compared with thermal energies. This article summarizes the future directions of PFA in electrophysiology, focusing on technological innovation, and how these advances are expected to expand PFA clinical indications. Additionally, this article provides a perspective on current gaps and future challenges of PFA. A perspective on future developments in new waveforms, catheter architectures, and integration with electroanatomical mapping systems for PFA is summarized. The document discusses novel waveform configurations and catheter design concepts that may improve lesion quality, procedural versatility, and safety. Additionally, this article also reviews how parallel advances in electroanatomical mapping integration, artificial intelligence, and robotic navigation are expected to enhance procedural guidance and enable individualized therapy. This manuscript summarizes the potential applications of PFA beyond pulmonary vein isolation and how emerging evidence supports its feasibility for linear atrial lesions, substrate modification, treatment of complex atrial tachycardias, and ventricular arrhythmia ablation. In addition, this article provides insights on how PFA may facilitate catheter ablation in new patient populations including elderly patients and those with higher procedural risks. Finally, this manuscript provides an outlook at major remaining challenges and knowledge gaps for PFA. The lack of homogenous procedural endpoints definitions and lesion durability assessment are discussed. Furthermore, this article highlights the need for standardized terminology and reporting in an environment where the high heterogeneity between available commercial systems complicates comparison across technologies.

Andrade et al. (2026) conducted a review in Cardiac arrhythmias (including atrial fibrillation, atrial tachycardias, and ventricular arrhythmias). Pulsed field ablation (PFA) vs. Thermal ablation (radiofrequency and cryothermal ablation) was evaluated. Pulsed field ablation demonstrates high procedural efficiency and safety for pulmonary vein isolation and is expanding to complex atrial and ventricular arrhythmias.
