CArdiac STereotactic Radiation Treatment for Ablation of ventRicular Tachycardia (CASTAR)
The investigator-initiated, CArdiac Stereotactic radiation Treatment for Ablation of ventRicular tachycardia (CASTAR) study will be conducted in patients with ventricular tachycardia (VT) which is either refractory to antiarrhythmic medication therapy in maximal dose or to catheter ablation or with contraindications to antiarrhythmic medication or catheter ablation.
The study is a non-randomized, multicenter, interventional study of cardiac SBRT, for which a total dose of 25 Gy will be delivered in a single fraction using volumetric modulated arc therapy (VMAT). The aim of the CASTAR study is to assess the feasibility and the safety of cardiac SBRT for the treatment of VT. Secondary objectives are efficacy, toxicity and QoL of cardiac SBRT for Ventricular tachycardia .

Szczegółowy opis
The study will be conducted at multiple centers across Belgium. Twenty patients will be enrolled to the study. Interim analyses are planned to be performed when the first five or ten subjects have been treated. Participation in the study will comprise a screening period, where screening assessments must be completed before starting treatment. Eligible, consenting patients will then undergo SBRT, which is limited to a single dose delivery on one day. During SBRT, patients are closely monitored in accordance with the DEGRO guidelines for radiotherapy in patients with ICDs (Gauter-Fleckenstein 2015). After SBRT, patients will be closely monitored during a 3-5 days hospitalization. The post-treatment phase will start after patients are discharged from the hospital. Patients will be followed on regular basis to assess safety and efficacy of SBRT treatment.

Opis
Inclusion Criteria:
- Patients over the age of 18 with structural heart disease
- Patients with ventricular tachycardia requiring intervention (e.g. an electrical shock or anti-tachycardia pacing via an Implantable Cardioverter Defibrillator (ICD)) which cannot be managed with medication or catheter ablation, or where there are contraindications to treatment with medication or catheter ablation.
- Contraindications may exist due to comorbidities or due to the type or severity of the disease.
- Informed consent to participate has been obtained from the patient or from his or her legal representative.
Exclusion Criteria:
- Lack of evidence that the ventricular tachycardia is triggered by myocardial scarring (based on MRI, CT EAM).
- Any contraindication to radiosurgery (e.g. inability to precisely define the target volume due to imaging artefacts caused by an LVAD)
- Pregnancy
- Previous radiotherapy that prevents the safe delivery of the dose.

Feasibility of SBRT for the treatment of ventricular tachycardia
Ramy czasowe: Day of SBRT treatment (Day 1)
|
Feasibility will be assessed as the successful implementation and completion of cardiac SBRT without interruption of treatment. SBRT consists of a single fraction of 25 Gy delivered to the ventricular tachycardia target. |
Day of SBRT treatment (Day 1)

|
Safety of SBRT for the treatment of ventricular tachycardia.
Ramy czasowe: From SBRT treatment through 31 days after SBRT
|
Safety will be assessed by the incidence and severity of adverse events related to radiotherapy following cardiac SBRT. Adverse events will be assessed and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0. |

Change in ventricular tachycardia burden following SBRT
Ramy czasowe: 6 months before SBRT through 6 months after SBRT
|
The ventricular tachycardia (VT) burden will be assessed by the number of VT episodes recorded by ECG and implantable cardioverter-defibrillator (ICD) readouts. The number of VT episodes during the 6 months following SBRT will be compared with the number during the 6 months preceding SBRT. A 6-week blanking period immediately following SBRT will be taken into account in the analysis of VT recurrences. |
6 months before SBRT through 6 months after SBRT
|
|
Time from SBRT to first VT recurrence
Ramy czasowe: From SBRT through 36 months after treatment
