Does a focal ablation catheter toggling between radiofrequency and pulsed field energy improve procedural efficiency, lesion durability, and freedom from atrial arrhythmias in patients with paroxysmal and persistent atrial fibrillation?
The use of a focal ablation catheter that toggles between radiofrequency and pulsed field energy is feasible and effective for treating paroxysmal and persistent atrial fibrillation.
AF ablation with a focal RF/PF catheter allows efficient procedures, chronic lesion durability, and good freedom from atrial arrhythmias-for both paroxysmal and persistent AF.
