Stereotactic radioablation for recurrent or nearly incessant slow ventricular tachycardia treatment

Endo-epicardial radiofrequency catheter ablation (RFCA) stands as a well-established treatment for recurrent ventricular tachycardia (VT) 1,2 , reducing appropriate implantable cardioverter defibrillator (ICD) shocks and managing electrical storms (ES) 3 .Single-session high-dose stereotactic-bodyradiation-therapy (SBRT) represents a non-invasive alternative to RFCA, having demonstrated VT burden reduction 4-7 .We designed a spontaneous, prospective, open-label study to validate SBRT in
