Ventricular Lesions
Ventricular lesions were created in the RV (4-6 applications/chamber) with lesions assigned to one of the 3 CTC cohorts prior to ablation. ICE and EAM were used to position lesions ≥20mm apart to prevent lesion overlap. Acute lesions were allowed to dwell for ≥2hrs prior to euthanasia to enable sufficient maturation10.
