  • SBRT for cardiac arrhythmias also termed stereotactic arrhythmia radioablation (STAR)
  • Stereotactic radioablation has been used to safely and effectively treat a limited number of patients with malignant arrhythmias:
    1. Ventricular tachycardia (VT)
    2. Atrial fibrillation (AF)
  • Unlike catheter-directed radiofrequency or cryoablation, in which tissue destruction is effected by thermal injury, radiotherapy uses gamma-rays or x-rays directed in high doses (typically 25–30 Gy) to a three-dimensional volume of target tissue
