Key Clinical MessageBipolar radiofrequency (RF) ablation is effective in treatment of ventricular tachycardia originating from thick interventricular septum. The RF generator and CARTO system can be used to precisely and safely perform ablation. Standard ablation catheter can be used with indifferent ablation electrode connected to the electrode receptacle in RF generator with custom‐made cable.

“…5 A recent study demonstrated that preprocedural MRIs in patients with failed VT ablations also helped to localise the arrhythmogenic tissue and thereby indicated the likelihood of whether an epicardial ablation was necessary. 30 In this study, patients with cardiac implanted electronic devices (CIEDs) were included.…”

Percutaneous catheter ablation has emerged as an effective treatment modality for the management of ventricular tachycardia. Despite years of progress in this field, the role of epicardial mapping and ablation needs to be further refined. In this review, we discuss the relationship between the type of underlying heart disease and the location of the arrythmogenic substrate as it pertains to a procedural approach. We describe the contribution of preprocedural and intraprocedural diagnostic tools for the localisation of the arrhythmogenic substrate, with a special emphasis on cardiac MRI and electrophysiological mapping. In our opinion, the preferred approach to target ventricular tachycardia should depend on the patient's underlying heart disease and the location of scar tissue, which can be best visualised using cardiac MRI.

“…[8][9][10][11][12] However, there have been no studies evaluating such techniques in refractory VAs exclusively in the NICM population. These studies have suggested improved outcomes with incorporation of epicardial access and ablation, or with the assistance of adjunctive tools, including advanced cardiac imaging and magnetic navigation technology.…”

Value of Cardiac Magnetic Resonance Imaging in Patients With Failed Ablation Procedures for Ventricular Tachycardia

Abstract: Imaging with DE-MRI prior to VT ablation in patients with previously failed endocardial ablation procedures is beneficial in identifying an ablation strategy, helps to focus on an area of interest intraprocedurally, and provides valuable outcomes information.
