Answer

Two major catheter-based modalities for isolating pulmonary venous triggers currently exist: radiofrequency ablation (RFA) and cryoballoon ablation. Cryoballoon ablation offers significantly shorter fluoroscopy and procedures times with similar efficacy as RFA in patients with paroxysmal AF. [133] Patients with persistent AF often require left atrial compartmentalization and ablation of nonpulmonary vein triggers; RFA is preferred in these scenarios.
