Endocardial low-voltage areas defined by the adjusted cutoff values corresponded better to LGE-detected scar than low-voltage areas defined by uniform cutoffs, which underestimated total scar and scare core in both patient groups. Participants who underwent successful ablation of ventricular tachycardia (n=15) contained >97% of all evoked delayed potentials applying the low-voltage area defined by remodeling-adjusted cutoffs; significantly smaller endocardial surface areas were covered when using uniform cutoffs. Finally, whole-heart T1-mapping revealed more fibrotic NIM in patients with remodeled vs nonremodeled LV, which may correspond to the marked decrease of endocardial voltage in patients with remodeled vs nonremodeled LV.
