5.4. Clinical Implication
LACV provides excellent prediction for AF recurrence after PVI. This
information will likely enable the differentiation of patients who need
additional left atrial ablation other than PVI from the majority of
patients who do not experience AF recurrence with PVI alone.
Nevertheless, LACV as measured in this study does not identify those
specific diseased areas whose ablation would improve rhythm outcomes.
Future studies are needed to explore the best ablation strategy in
patients with a slow LACV.
