Cost, long-term efficacy, and integration with existing mapping systems will be key determinants for its adoption over current approaches. This must be kept in mind as newer PFA technologies make their way into the clinical realm. The pulsed-field strength remains independent of tissue contact; therefore, PFA is assumed to be an ablation technology, not mandating the need for tissue contact. DOI: 10.1097/HCO.0000000000000810 Abstract Purpose of review: Pulsed field ablation is a nonthermal ablative modality that uses short living, strong electrical field created around catheter to create microscopic pores in cell membranes (electroporation). PFA is an ablation technique that consists in subjecting the tissue to brief high electric field exposures. These data mitigate concern that the nonthermal ablative mechanism of PFA might mask undiscovered compromises to clinical success. which was performed to ensure a left ventricular ejection fraction of 35% and no gross enlargement of the left atrium >5cm. An official website of the United States government. Pulsed-field ablation (PFA) is a non-thermal ablation technology that uses high amplitude pulsed electrical fields to ablate tissues through the mechanism of irreversible electroporation. As PFA is a novel form of ablation which uses electrical fields to ablate cardiac tissue, the authors note that there is currently limited data on assessing the safety of this ablation method in humans.
