Efficacy of Ablation with Follow-up
Freedom from atrial arrhythmia at one year of follow-up in the total cohort was 68.2%. Patients undergoing repeat ablation for atypical AFL had significantly higher arrhythmia free survival rate (75.5 vs. 65.0 %, p=0.04) as compared to patients undergoing repeat ablation for AF (Figure 2) at one year of follow-up.
