Key result
Ablation for symptomatic drug-refractory atrial fibrillation resulted in 73% of patients being AF-free at 12 months, with higher success in paroxysmal (80%) than persistent AF (64%).

Does ablation prevent atrial fibrillation recurrence in patients with symptomatic drug-refractory paroxysmal or persistent atrial fibrillation?
Absolute Event Rate: 80% vs 64%
Ablation is highly effective for drug-refractory atrial fibrillation, with higher success rates in paroxysmal versus persistent AF, as confirmed by rigorous 1-year continuous subcutaneous monitoring.
Pokushalov et al. (2010) conducted an observational in Paroxysmal or persistent atrial fibrillation (n=129). Ablation (Paroxysmal AF group) vs. Ablation (Persistent AF group) was evaluated on AF-free 12 months after the last ablation procedure. Ablation for symptomatic drug-refractory atrial fibrillation resulted in 73% of patients being AF-free at 12 months, with higher success in paroxysmal (80%) than persistent AF (64%).
