We describe the 10-year outcome of the first-in-human series of 12 patients with hypertrophic cardiomyopathy treated with alcohol septal ablation. There was no 30-day mortality. Survival free of death, internal cardiac defibrillator discharge for treatment of ventricular fibrillation or tachycardia, severe New York Heart Association (NYHA) class III/IV and/or Canadian Cardiovascular Society class III/IV symptoms and the need for surgical myectomy in this cohort was 91% at 1 year and 73% at 10 years. The reduction in outflow tract gradient was maintained over the 10 years, from a mean preoperative gradient of 70 mm Hg to a median of 3 mm Hg at 126 months of follow-up (p < 0.01). Two patients (16%) underwent a further ablation procedure. Two patients (16%) suffered sudden cardiac death, 91 and 102 months after the procedure. Long-term symptom benefit was experienced by all patients, with a reduction in mean NYHA class from 2.7 +/- 0.6 before the procedure to 1 after the procedure at the last follow-up (p < 0.01). This historic small cohort study demonstrates that septal ablation can provide long-term haemodynamic and symptomatic benefit.
