[Guideline to safe and effective atrial fibrillation ablation with pulsed-field ablation using the pentaspline PFA system as an example].

Atrial fibrillation ablation is an established procedure for the treatment of atrial fibrillation, in which Pulsed Field Ablation (PFA) is a novel method alongside radiofrequency and cryoablation. The article explains the technical basics of PFA, describes different types of catheters and gives detailed instructions on how to perform the procedure, from patient selection to sedation strategies and imaging. Important safety aspects and possible complications are also covered. Finally, the further development of PFA technology for the treatment of other arrhythmias and integration into 3D mapping systems is discussed. This work is part of a series of articles on further training in special rhythmology.
