Eligibility Criteria

Inclusion

  • Patients with structural heart disease and implantable cardioverter defibrillator (ICD)
  • Age \> 18 years
  • either
  • Recurring symptomatic monomorphic ventricular tachycardia that requires ICD intervention (e.g. shock or anti-tachycardia stimulation). At least 3 episodes within the 3 months prior to inclusion or
  • induction of symptomatic monomorphic ventricular tachycardia that requires ICD intervention (e.g. shock or anti-tachycardia stimulation). Induction triggered by ICD or during electrophysiology studies (EPS) or both, a) and b)
  • Refractory to antiarrhythmic combination therapy
  • Beside the cardiac conditions: No competing illness that would additionally limit the life expectancy to less than 6 months
  • No prior radiation therapy in the thorax area
  • No pregnancy and no active breastfeeding
  • Ability to consent and consent to study participation

Exclusion

  • ICD electrode malfunction of ICD readings outside reference range
  • Lack of evidence of a myocardial scar (Computer tomography or magnetic resonance tomography for MRI-capable ICD aggregates or electrophysiological measurement)
  • No possible induction of symptomatic monomorphic ventricular tachycardia non-persistent or persistent with delivery of ICD therapies such as antitachycardic pacing or shock
  • Contraindication to radiosurgery (e.g. precise target volume definition not possible due to image artifacts created from a left ventricular assist device (LVAD))
  • Inability to consent or missing or withdrawn consent
