Key result
Stereotactic body radiation therapy successfully treated premature ventricular complex-induced cardiomyopathy in the right ventricle of a patient with a mechanical tricuspid valve.
Why the study?
SBRT is an option for ventricular arrhythmias when substrate is not amenable to classic approaches, but its use for RV PVCs in the presence of a mechanical tricuspid valve had not been described.
Does stereotactic body radiation therapy (SBRT) successfully treat premature ventricular complexes originating in the right ventricle in a patient with a mechanical tricuspid valve?
Does stereotactic body radiation therapy (SBRT) successfully treat premature ventricular complexes originating in the right ventricle in a patient with a mechanical tricuspid valve?
SBRT can be a successful alternative treatment for PVC-induced cardiomyopathy when traditional catheter ablation is precluded by anatomical barriers such as a mechanical tricuspid valve.

Hypothesis-generating for SBRT in right ventricular PVC-induced cardiomyopathy with mechanical tricuspid valve; prospective trials needed before clinical adoption.
Stereotactic body radiation therapy (SBRT) for ventricular tachycardia is a treatment option for selected patients with substrate not amenable to classic approaches. We present a case of successful SBRT in a patient with premature ventricular complex (PVC)-induced cardiomyopathy originating in the right ventricle (RV) in whom access to the RV was limited by a mechanical tricuspid valve.
