%X <B>UNASSIGNED: </B>Stereotactic arrhythmia radioablation (STAR) is an effective treatment for refractory ventricular tachycardia (VT), but recurrences after STAR were recently published. Herein, we report two cases of successful re-irradiation of the arrhythmogenic substrate.<BR><B>UNASSIGNED: </B>We present two cases of re-irradiation after recurrence of a previously treated VT with radioablation at a dose of 20 Gy. The VT exit was localized on the border zone of the irradiated volume, which responded positively to re-irradiation at follow-up.<BR><B>UNASSIGNED: </B>These two cases show the technical feasibility of re-irradiation to control recurrent VT after a first STAR.
