Targets were identified based on wall thickness heterogeneity. After image integration, ablation with &gt;\u200910 grams, 40\u201350\u2009W was performed with the aim of blocking the CT channels\/render them non\u2010capturable.

The mean number of identified CT Channels was 3.6\u2009\u00b1\u20091.8\/patient. Non\u2010inducibility was achieved in 19 (48.7%) of patients after initial imaging\u2010guided ablation, while at least one VT could be induced in 19 (48.7%). Among these patients, 4 had VT related to unblocked or reconnected CT\u2010determined VT channels, and 15 from other areas (border zone), typically with faster cycle length. After further mapping and ablation, 3 (7.7%) patients remained inducible.
