Figure 3. Transformation to persistent AF and late AF/AT recurrence
Proportion of patients who developed AF/AT recurrence in persistent form in each group are compared (A). Patients with LVAs (group B and C) demonstrated higher rates of transformation to persistent AF than those without (group A). Proportion of patients with late AF/AT recurrence defined as recurrence > 6 months after the initial ablation are shown (B). Patients with LVAs experienced more late recurrence than those without. AF indicates atrial fibrillation; AT, atrial tachycardia.
