BackgroundAtrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide, posing significant health burdens. Pulsed field ablation (PFA) is an emerging non-thermal technique that is gaining traction due to the ability to selectively target myocardial cells and minimize damage to surrounding tissues.

Atrial fibrillation is the most prevalent arrhythmia with a lifetime risk of nearly 30%. It can be associated with reduced quality of life and complications such as heart failure and stroke. Pulmonary vein isolation (PVI) is the most effective treatment for rhythm control. It has initially been performed with fluoroscopic catheter guiding.
