Why the study?
Long-term outcomes of preventive cavotricuspid isthmus ablation in patients with risk factors for typical atrial flutter were not well established.
Does preventive cavotricuspid isthmus ablation prevent typical atrial flutter in patients with paroxysmal atrial fibrillation and risk factors undergoing pulmonary vein isolation?
Cohort (n=42)
Does preventive cavotricuspid isthmus ablation prevent typical atrial flutter in patients with paroxysmal atrial fibrillation and risk factors undergoing pulmonary vein isolation?
Preventive cavotricuspid isthmus ablation during pulmonary vein isolation in patients with risk factors prevents typical atrial flutter without significantly increasing complications, though it slightly prolongs procedure time.

Safonov et al. (2021) conducted a cohort in Paroxysmal atrial fibrillation with risk factors for typical atrial flutter (n=42). Pulmonary vein isolation with simultaneous cavotricuspid isthmus ablation vs. Pulmonary vein isolation alone was evaluated on Freedom from atrial fibrillation recurrence at 1 year.
