Key result
Stereotactic radioablation suppresses refractory VT in a patient with double mechanical valves.
Why the study?
Catheter ablation for left ventricular tachycardia is technically challenging in patients with mechanical aortic and mitral valves due to limited LV access, prompting exploration of alternative therapies.

Stereotactic radioablation therapy may serve as a viable bailout option for refractory ventricular tachycardia in patients with inaccessible left ventricles due to double mechanical valves.
May support stereotactic radioablation as bailout for refractory VT in inaccessible LV; hypothesis-generating, needs prospective validation.
In patients with mechanical aortic and mitral valves and left ventricular (LV) tachycardia (VT), catheter ablation is technically challenging due to the limited access to the LV. Promising new alternatives to radiofrequency ablation include pulsed-field electroporation, percutaneous or surgical sympathetic neuromodulation, and noninvasive stereotactic radioablation therapy (SBRT). We herein describe the effect of SBRT as a bailout therapy on the management of a challenging VT case in the presence of double left-sided mechanical valves.

Aras et al. (2021) conducted a case report in Refractory ventricular tachycardia (n=1). Stereotactic radioablation therapy (SBRT) was evaluated on Reduction in ventricular tachycardia episodes. Stereotactic radioablation therapy delivered at 25 Gy significantly reduced refractory ventricular tachycardia episodes in a patient with double mechanical valves and a no-entry left ventricle.
