Outcome of Alcohol Septal Ablation in Mildly Symptomatic Patients With Hypertrophic Obstructive Cardiomyopathy: A Long-Term Follow-Up Study Based on the Euro-Alcohol Septal Ablation Registry

Original language description

Background-The long-term efficacy and safety of alcohol septal ablation (ASA) in patients with highly symptomatic hypertrophic obstructive cardiomyopathy has been demonstrated. The aim of this study was to evaluate the long-term outcomes of mildly symptomatic patients with hypertrophic obstructive cardiomyopathy treated with ASA. Methods and Results-We retrospectively evaluated consecutive patients enrolled in the Euro-ASA registry (1427 patients) and identified 161 patients (53 +/- 13 years; 27% women) who were mildly symptomatic (New York Heart Association [NYHA] class II) pre-ASA. The median (interquartile range) follow-up was 4.8 (1.7-8.5) years. The clinical outcome was assessed and compared with the age-and sex-matched general population. The 30-day mortality after ASA was 0.6% and the annual all-cause mortality rate was 1.7%, which was similar to the age-and sex-matched general population (P=0.62). A total of 141 (88%) patients had resting left ventricular outflow tract gradient at the last clinical checkup &lt;= 30 mm Hg. Obstruction was reduced from 63 +/- 32 to 15 +/- 19 mm Hg (P&lt;0.01), and the mean NYHA class decreased from 2.0 +/- 0 to 1.3 +/- 0.1 (P&lt;0.01); 69%, 29%, and 2% of patients were in NYHA class I, II, and III at the last clinical checkup, respectively. Conclusions-Mildly symptomatic hypertrophic obstructive cardiomyopathy patients treated with ASA had sustained symptomatic and hemodynamic relief with a low risk of developing severe heart failure. Their survival is comparable to the general population.
