Successful Application of Stereotactic Body Radiation Therapy for Ventricular Tachycardia Substrate in a Patient With Nonischemic Cardiomyopathy

Am J Cardiol. 2022 Dec 1:184:149-153. doi: 10.1016/j.amjcard.2022.08.017. Epub 2022 Sep 24.

Abstract

Cardiac stereotactic body radiotherapy (SBRT) has been gaining attention as a potential treatment for patients with ventricular tachycardia (VT). Here, we describe a nonischemic patient with severe heart failure and VTs originating from the deep anteroseptal substrate that was refractory to standard and bipolar catheter ablations, and was successfully managed with SBRT. In conclusion, anteroseptal VTs resistant to catheter ablation in severe nonischemic heart failure might be an indication for cardiac SBRT as palliative therapy.
