摘要

Discordances in detected pathological substrate exist between LVS, CV and LGE-MRI in the LA, irrespective of the LGE detection method. The new EOIIT method improves concordance of LGE-MRI-based ACM diagnosis with LVS in ablation-naive AF patients but discrepancy remains particularly on the posterior wall. All methods may enable prediction of rhythm outcome after PVI in patients with persistent AF.
