Why the study?
Limited treatment options exist for patients with potentially life-threatening ventricular tachycardia refractory to catheter ablation, anti-arrhythmic drugs, and ICDs.
Stereotactic arrhythmia radioablation (STAR) offers a novel, non-invasive multidisciplinary treatment option for patients with refractory ventricular tachycardia.
Ventricular tachycardia(VT) is a wide complex tachyarrhythmia which could be potentially life-threatening. Standard treatment options include catheter ablation, anti-arrhythmic drugs and ICDs (Implantable cardioverter defibrillator). In patients refractory to the above treatments, limited options are available. Stereotactic arrhythmia radio-ablation (STAR) is a novel non-invasive method of ablating the arrhythmogenic substrate using high dose of highly focused radiotherapy. This technique requires a multi-disciplinary team consisting of Cardiologist, Electrophysiologist, Radiation oncologist and Radiologist to integrate pre-treatment imaging and electro-physiological data to generate a target that can be radiated. Studies show excellent control of VT, 6–12 weeks post-treatment with no major toxicities. This article attempts to provide a practical step by step approach to stereotactic arrhythmia radioablation.
