Recurrent AF/AT
AF/AT recurrence was observed in 104 (25.9%) patients after the initial
ablation, with higher recurrence rates in patients with LVAs (group B+C)
than in those without (group A, Figure 2A and Table 1). No difference
was observed between group B and C. All patients developed AF/AT
recurrence in group D. Multivariate analyses of patients having complete
voltage maps revealed that female, large left atrial diameter, and LVA
presence were independently associated with AF/AT recurrence (Table 2).
Among patients with LVAs, large left atrial diameter was the only
associated factor (Table 3).
Transformation from paroxysmal AF to persistent AF was more frequently
observed in patients with LVAs (group B+C) than in those without (group
A, Figure 3A). In addition, patients with LVAs (group B+C) more
frequently experienced late AF/AT recurrence, defined as recurrence at
> 6 months after the last ablation, than those without
(group A, Figure 3B).
