Multimodal images integration for catheter ablation of ventricular tachycardia

Abstract : Radiofrequency catheter ablation is an important therapeutic option for patients with recurrent ventricular tachycardia (VT). The procedure aims at cauterizing regions of the ventricle. A good knowledge of anatomical structures and tissues properties can improve procedure safety and efficacy. This work aimed at analysing the feasibility of a workflow based on multimodal image integration to assist the intervention. We focused here on a model including myocardial thickness and fibrosis extracted from late gadolinium enhanced MRI (LGE-MRI) sequence, and left ventricular anatomy segmented from multiphase computed tomography (CT). The produced model can be imported within Carto-3® system (Biosense Webster Inc, Diamond Bar, CA), the software used during the ablation procedure. Four patients cases have been included in this preliminary study. The four produced patient specific models have been validated by a clinician, and two of them have been integrated within Carto-3® system and used during the intervention. © 2017 IEEE Computer Society.
