Ventricular tachycardia storms and fibrillation are potentially lethal arrhythmias with limited treatment options. Failed catheter ablation is associated with a fourfold mortality increase in this population. Stereotactic body radiotherapy has been proposed as last resort in these patients. We report a patient in whom radiotherapy was safely performed leading to the elimination of ventricular arrhythmia during a one- year- follow- up period.
