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.
