Abstract
Patients with recurrent ventricular tachycardia (VT) are treated with antiarrhythmic drugs and invasive catheter ablation(s).1 Unfortunately, though some patients have an (urgent) indication for invasive catheter ablation, coexisting conditions may prohibit such procedures. Cardiac radioablation, or stereotactic arrhythmia radiation therapy, is a new and promising noninvasive treatment modality for patients considered therapy-refractory or untreatable.2 Although the mechanism of action of cardiac radioablation remains to be elucidated, based on previous data the antiarrhythmic effects of cardiac radioablation could take several weeks to several months.
