4.6 Clinical implications
As we previously reported, the AF drivers were mainly be located in
heterogenous LGE areas, which could be detected by
LGE-MRI.7 Preprocedural LGE-MRI could evaluate the LA
wall thickness as well as LGE areas precisely and would be useful to
predict the AF drivers in the lesser LGE area. This would help in
planning where to ablate in addition to the PVI at a point before the
ablation procedure and might reduce frequent electrophysiological
mapping. We believed that this would make a significant contribution to
the realization of an AF ablation with a higher specificity. Finally, we
strongly recommended that thinner AWT areas in lesser LGE areas should
be excluded from the ablation targets.
