Brief Summary:
This double arm randomized study will compare 2 ventricular tachycardia ablation strategies: the standard strategy based on invasive substrate and VT mapping with 3D electro-anatomical system vs a tailored strategy which identifies targets based on pre-procedural CT-scan imaging. The primary endpoint will be procedure duration and secondary endpoints will include safety and efficacy criteria as well as medico-economic evaluation.
Detailed Description:
Ventricular tachycardia ablation is a non-drug alternative for patients with recurrent VT and ischemic cardiomyopathy with a class 1 indication in the latest guidelines. However, it is poorly standardised and reserved to expert centres. Proof of concept studies have demonstrated that image-guided VT ablation is feasible, and that it may improve the efficiency of VT ablation.
Ablation strategy no longer relying on intracardiac 2-dimensional surface catheter measurements for target identification, but on 3- dimensional pre-operative images of the myocardium acquired by computed tomography (CT) would shorten the procedure, make it more reproducible and less dependent of the operator's experience without altering efficacy.
This randomized study will compare VT ablation based on substrate/VT isthmus identification via intracardiac catheter vs identification via pre-procedural CT-scan. Ablation will be performed with the same material.
Primary endpoint will be procedure duration. Secondary endpoints will compare efficacy and safety of both strategies as well as cost-effectiveness.
Expected results are a reduction procedure duration, without alteration of the efficacy for the CT-guided procedure with an improved medico-economic evaluation.
