This case highlights that alcohol septal ablation for HOCM can be complicated by scar-induced reentrant sustained ventricular tachycardia, a rare but significant complication.

Alerts clinicians to monitor for scar-related VT post-alcohol septal ablation in HOCM; single case leaves open incidence and prevention needs.
A 49-year-old man with a history of hypertrophic obstructive cardiomyopathy (HOCM) presented in sustained monomorphic ventricular tachycardia (SMVT) 8 days post-alcohol septal ablation. A dual chamber implantable cardioverter defibrillator ICD was implanted and the patient experienced another episode of VT 3 weeks later, which was terminated by an ICD shock. This case demonstrates probable scar-induced reentrant VT post-alcohol septal ablation, a likely rare but hypothesized complication of this procedure.
