Primary Outcome Measures
NameTimeMethod
To demonstrate acute safety of delivering STAR. Side effects possibly, probably or definitely related to study treatment are registered conform CTCAE v5.0. The incidence of grade 3 and above toxicity should be = 33.33% within 90 days of treatment.
Secondary Outcome Measures
NameTimeMethod
•Reduction in VT burden defined by decline in ICD therapy in shocks and/or ATP compared to the 6 months period prior to STAR (or shorter if ICD information is lacking), <br>•Changes in antiarrhythmic medication due to treatment effects.<br>•Changes in patient reported quality of life (recorded as EQ 5D 5L).<br>•Report late toxicity after 90-days post intervention (according to CTCAE v5.0)<br>
