Ablation strategies promising AF termination and eliminating
recurrence
To determine the ablation strategy associated with terminating AF and
maintaining SR, a total of 241 persistent AF patients who underwent
catheter ablation were recruited from the Kobe University AF registry
database. Based on the ablation summary, the patients were classified
into the following four groups: 1) PVI group, 2) PVI plus substrate
modification including linear, CFAE and LVZ ablation group (PVI plus SM
group), 3) PVI plus Box lesion group (Box lesion group) and 4) PLS
ablation group. The ratio of AF termination and AF recurrence during the
follow-up period were assessed among four groups.
