NCT03867747

Brief Summary

Patients with refractory ventricular extrasystoles or tachycardia not eligible for catheter ablation will receive single fraction stereotactic body radiation therapy (cardiac radiosurgery) with 25 Gy. Investigators initiated this study to demonstrate that in at least 70% of the patients the planned cardiac radiosurgery may be performed without any interruption or treatment related interventional events within the first 30 days after treatment.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with structural heart disease and implantable cardioverter defibrillator (ICD)
  • Age \> 18 years
  • either
  • 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

You may not qualify if:

  • 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  • Inability to consent or missing or withdrawn consent
