Brief Summary

The investigators hypothesize that preventive VT substrate ablation in patients with chronic ICM, previously selected based on imaging criteria (BZC mass) for their likely high arrhythmic risk, is safe and effective in preventing clinical VT events.

Study Arms (2)

ABLATE arm

EXPERIMENTAL

Ventricular tachycardia substrate ablation intending to: i) eliminate all the potential arrhythmogenic substrate, aiming for complete electrical isolation/elimination of all the electrograms with delayed components or showing hidden slow conduction properties, and ii) non-inducibility or ventricular tachycardias at the end of the procedure. Standard medical treatment will also be given for these patients.

Procedure: Ventricular tachycardia substrate-based radiofrequency ablation

NO-TREAT arm

NO INTERVENTION

Only standard medical treatment will be offered for these patients.

Interventions

Ventricular tachycardia substrate-based radiofrequency ablation PROCEDURE

The CARTO3 electroanatomic navigation system (Biosense Webster, Diamond Bar, CA, USA) will be used for ablation. An open irrigated 3.5-mm tip ablation catheter (ThermoCool SmartTouch, Biosense Webster, Diamond Bar, CA, USA) will be used for mapping and ablation. The first step of the procedure will be the acquisition of a fast-anatomical map (FAM) of the aorta. This FAM will be then used to integrate the multi-detector cardiac tomography (MDCT) reconstruction and cardiac magnetic resonance (CMR)-derived pixel-signal intensity (PSI) maps within the spatial reference coordinates of the CARTO3 system. RF will be delivered at the entrance of the border zone channels (BZCs) identified in the PSI maps (CMR-guided scar dechanneling technique). Programmed ventricular stimulation (PVS) will be always performed after substrate elimination to test for final inducibility.
