Electroanatomical mapping–guided stereotactic radiotherapy for right ventricular tachycardia storm

We present the case of a patient who presented in a dire situation with ventricular tachycardia (VT) storm, which did not respond to intubation, antiarrhythmics, or catheter ablation. This presentation is in the background of palliatively treated metastatic malignancy. We needed a strategy to treat VT to enable the step-down from intensive care and to restart systemic palliation. To that end we employed a strategy of electroanatomical mapping–guided stereotactic body radiotherapy (SBRT) with good effect.
