Key result
Pulsed field ablation improves AF ablation safety and efficiency over thermal energy via tissue selectivity.
Why the study?
Pulsed field ablation offers a nonthermal, tissue-selective alternative to conventional thermal energy for atrial fibrillation ablation, requiring mechanistic and engineering insights to establish its safety and efficacy.
This review summarizes the mechanistic insights and engineering advances of pulsed field ablation, positioning it as a safer and more precise alternative to thermal ablation in cardiac electrophysiology.
May support pulsed field ablation evaluation in atrial fibrillation; leaves open comparative safety and efficacy versus thermal ablation in randomized trials.
Pulsed field ablation has rapidly reshaped the landscape of atrial fibrillation ablation by offering a nonthermal, tissue-selective alternative to conventional thermal energy. This review highlights the scientific foundations, preclinical evidence, and engineering advances that established pulsed field ablation as a safer, faster, and more precise technology. We discuss how irreversible electroporation achieves myocardial selectivity, the pivotal studies that confirmed preservation of nearby structures, and the evolution of modern catheter systems designed for efficient and durable lesion creation. As pulsed field ablation platforms continue to mature, they are redefining procedural safety standards and expanding therapeutic possibilities in cardiac electrophysiology.
