Pulsed field ablation is an emerging nonthermal technology for atrial fibrillation that may offer shorter procedural times and fewer major complications compared to traditional thermal ablation.
This review topic provides an overview of a novel technique for catheter ablation in patients with atrial fibrillation (AF) called pulsed field ablation. Pulsed field ablation uses a nonthermal vs thermal approach (radiofrequency or cryoablation) for obtaining myocardial cell death, which is referred to as irreversible electroporation for the treatment of AF via pulmonary vein isolation. This emerging technology delivers microsecond high-voltage electrical fields that may limit damage to tissues outside the myocardium and offers a promising approach to managing AF with shorter procedural times and fewer major complications. This review aimed to educate allied health professionals regarding this evolving technology by summarizing the biophysics of irreversible electroporation, clinical evidence supporting pulse field ablation, associated complications, and future applications.
