ABSTRACT
BACKGROUND:
Alcohol septal ablation (ASA) is an alternative treatment for symptomatic hypertrophic obstructive cardiomyopathy (HOCM) patients refractory to pharmacological therapy. We sought to evaluate the immediate and long-term incidence of death and changes in life quality in a consecutive cohort submitted to ASA. METHODS ANDRESULTS:
Between October 1998 and December 2013, a total of 56 patients (mean age 53.2 ± 15.5) with symptomatic refractory HOCM were treated with ASA and followed during 15 years (mean 8 ± 4 years). There were 7 (12.5%) deaths, 2 (3.6%) being of cardiac cause. The Kaplan-Meier survival probability estimate was 96.4% at 1 year, 87.7 at 5 years and 81.0% at 12 years post-ASA. Significant improvement was observed in life quality assessed by DASI index and NYHA functional class as well as in the left ventricle outflow tract (LVOT) gradient reduction (from 92.8 ± 3.3 mm Hg to 9.37 ± 6.7 mm Hg, P < 0.001) and septum thickness (from 23.9 ± 0.6 mm to 12.9 ± 1.0 mm, P < 0.001). Only one patient (1.7%) required permanent pacemaker immediately after ASA. During follow-up, one patient had a repeated ASA...
