Empirical Cavotricuspid Isthmus Ablation in Congenital Heart Disease: A Nationwide Prospective Study.

BACKGROUND Recurrence rates of atrial arrhythmias after catheter ablation in patients with congenital heart disease (CHD) remain substantial. Given the high prevalence of peritricuspid flutter, systematic cavotricuspid isthmus (CTI) ablation may represent a rational preventive strategy. OBJECTIVES The objective of th...

Algorithm-guided personalized pulsed field ablation for persistent atrial fibrillation: a prospective multicentre study with matched external comparison

PFA was delivered mainly in the flower configuration until complete regional coverage of the highlighted areas, avoiding gaps between targeted areas and/or anatomical boundaries. If AF persisted, re-mapping and further ablation of the new highlighted areas could be performed. AF termination was defined as direct restor...

Characteristics of Recurrent Atrial Arrhythmias and Lesion Assessment Late After Pulsed Field Ablation of Atrial Fibrillation

In patients undergoing redo procedures after an initial AF ablation using the pentaspline PFA catheter, AF was less frequently observed when ablation lesions were performed beyond PVs and a high rate of durable PVI or block was achieved with >12 PFA applications per PV and >16 for the roof/PW.
