Cardiac radioablation (CR) has recently emerged as a therapeutic option to treat cardiac arrhythmias in patients with recurrent ventricular tachycardia (VT) after being treated using the standard workflow, including antiarrhythmic drugs and/or catheter radiofrequency ablation [1]. CR involves the delivery of a single 25 Gy dose to the cardiac substrate identified as the source of abnormal electrical propagation. Both C-arm linear accelerators (linacs) (Elekta and Varian platforms) and the CyberKnife robotic system (Accuray), which are typically implemented for stereotactic body radiotherapy (SBRT), have been considered for CR of VT [2,3].
