PAM-VT 2 Study: Long-Term Scar Evolution and Ablation Lesion Assessment by Late Gadolinium Enhancement Cardiac Magnetic Resonance After Ventricular Tachycardia Ablation
Postablation LGE-CMR reveals durable changes in scar characteristics, with early scar evaluation at 3 to 6 months strongly associated with long-term VT recurrence. The reduction in scar heterogeneity and conducting channels is sustained over time, underscoring the usefulness of LGE-CMR for assessing ablation success. Additionally, VT ablation appeared to be associated with favorable reverse remodeling, highlighting potential benefits beyond arrhythmia control. These findings support the use of LGE-CMR for personalized management following VT ablation.
