Rhythm outcomes after multiple ablations
After a mean of 1.2 ± 0.5 ablations,
AF/AT recurrence developed in 49 (12.2%) patients. AF/AT recurrence
rates after multiple ablations in treatment cohorts are compared in
Figure 2B. Patients with LVAs at the initial procedure (group B+C)
demonstrated more frequent AF/AT recurrence even after multiple
ablations. AF/AT recurrence rates were comparable between those with
(group B) and without LVA ablation (group C).
At the time of the final out-patient clinic, 19 (4.7%) patients were
taking anti-arrhythmic drugs (Table 1). The proportion of patients with
sinus rhythm on ECG at that time was significantly higher in patients
without LVA (group A) than in those with (group B+C), although there was
no difference between groups B and C.
