Abstract
Pulsed field ablation (PFA) offers a novel approach to treating atrial fibrillation, demonstrating promising efficacy and safety. Unlike traditional thermal ablation techniques like radiofrequency or cryoablation, PFA uses non-thermal irreversible electroporation to selectively target myocardial tissue, minimizing damage to surrounding structures such as the oesophagus, phrenic nerve, and coronary arteries. Initial studies indicate that PFA is effective in achieving durable pulmonary vein isolation and posterior wall isolation, with a low incidence of serious complications. However, more long-term clinical data are needed to further confirm its efficacy.
