VIDEO: Cardiac Radiotherapy Ablation to Treat Ventricular Tachycardia

Clifford Robinson, M.D., associate professor of radiation oncology, chief of the SBRT service, director of clinical trials, Washington University, St. Louis, Washington University School of Medicine in St. Louis, explains the longer term results of cardiac radiotherapy ablation to treat ventricular tachycardia. Image-guided cardiac radioablation dramatically reduces episodes of fast, abnormal heartbeats for more than two years in the ENCORE-VT trial.

In collaboration with Phillip Cuculich, M.D., associate professor of cardiology and radiation oncology at the Washington University School of Medicine in St. Louis, Robinson and his team developed a noninvasive, outpatient procedure for treating VT called EP-guided noninvasive cardiac radioablation (ENCORE-VT). This novel therapy fuses electrical (ECGs) and imaging (computed tomography, magnetic resonance imaging, positron emission tomography) data to pinpoint the scar tissue in the patient’s heart responsible for the arrhythmias, then targets it with a single dose of stereotactic body radiation therapy (SBRT), a type of high-dose radiation most commonly used to treat patients with cancer. ENCORE-VT requires no general anesthesia and allows patients to go home immediately after treatment. 

The results of the ENCORE-VT study were presented at ASTRO 2019. The results were also presented as a late-breaking trial at the Heart Rhythm Society (HRS) 2020 virtual meeting.
