Ventricular arrhythmia ablation lesions detectability and temporal changes on cardiac magnetic resonance

Conclusion: Ventricular ablation lesions visualization is negatively affected by preexisting transmural scar, ICD artifact and low EF. The transition of “black” MVO appearance to “white” LGE appearance on CMR occurs around 1 month following ablation, suggesting a change in histological characteristics of ablation lesions. This may affect the utility of CMR in the evaluation of the ventricular lesions, when undergoing real‐time or repeat VT ablations.This article is protected by copyright. All rights reserved
