Abstract
The ablation of cardiac arrhythmias is now standard therapy in invasive electrophysiology with afocus on atrial fibrillation due to its high prevalence. Thermal energy sources such as radiofrequency or cryoablation are the most commonly used techniques to date. Due to limitations in terms of effectiveness and safety because of possible indiscriminate tissue destruction, ablation using pulsed field ablation (PFA) can be asafe and effective alternative to thermal ablation techniques. This is anonthermal form of energy that creates effective myocardial lesions by means of irreversible electroporation by generating short, high-energy electrical impulses. Preliminary data show high effectiveness with alow complication rate. Myocardial tissue shows ahigh specificity while sparing surrounding structures such as the esophagus, the phrenic nerve and surrounding vascular structures. Therefore, irreversible electroporation is a very promising technique and has the potential to become the perfect form of energy for many catheter ablations and especially for pulmonary vein isolation. In this article we provide an overview of the current status of PFA as well as an outlook on future fields of treatment.
