In the last few years novel ablative technologies featuring several devices incorporating different energy sources and catheter design for ensuring an effective PVI have been proposed. In particular, two prominent technologies, such as the non-thermal ablation modality based on pulsed field ablation (also defined as “electroporation”) and radio frequency balloon-based catheter has been introduced in the clinical practice. The adoption of such technologies aims at simplifying PVI procedures, improving efficacy, and increasing safety. Furthermore, the evaluation of the extension of area of lesion promoted by the two technologies might affect the clinical outcome
