Overview
Most electrophysiologists who perform catheter ablation procedures for treatment of atrial fibrillation (AF) believe rotors have a role in maintaining AF, but it is not clear how much of a role or in what proportion of cases. Recent literature has shown varying outcomes using focal impulse and rotor modulation (FIRM)-guided ablation. Some of the factors potentially responsible for these inconsistent results include variability among operators in: rigor of basket catheter positioning; confidence in diagnosing the presence and locations of focal sources; and amount of ablation performed in regions designated as having rotors or foci. In this webinar, we will: give some background of the basis of rotor-guided ablation of AF; set forth different workflows used during procedures; and attempt to address some of the current controversies in rotor mapping and ablation.
