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.
