Does noninvasive ablation with stereotactic body radiotherapy improve outcomes in patients with right ventricular tachycardia storm?
Stereotactic body radiotherapy is a novel, safe, and effective short-term option for right ventricular tachycardia storm, but requires consideration of anticoagulation due to thromboembolism risk.
May support short-term radiotherapy ablation of RV free wall in refractory VT; leaves open long-term safety and thromboembolism risks.
Key Teaching Points•Fast and irregular ventricular tachycardia with hemodynamic compromise could occur in a structurally normal heart.•Use of noninvasive ablation with radiotherapy on the right ventricular (RV) free wall is novel.•Ablation of the RV free wall using radiotherapy is safe and effective in the short term.•Stereotactic body radiotherapy could carry the risk of thromboembolism; hence anticoagulation needs to be considered. •Fast and irregular ventricular tachycardia with hemodynamic compromise could occur in a structurally normal heart.•Use of noninvasive ablation with radiotherapy on the right ventricular (RV) free wall is novel.•Ablation of the RV free wall using radiotherapy is safe and effective in the short term.•Stereotactic body radiotherapy could carry the risk of thromboembolism; hence anticoagulation needs to be considered.
