Predictors of outcome after alcohol septal ablation in patients with hypertrophic obstructive cardiomyopathy. Special interest for the septal coronary anatomy

<p>Alcohol septal ablation (ASA) provides symptomatic relief in most but not all patients with hypertrophic obstructive cardiomyopathy (HOCM). Therefore we investigated predictors of outcome after ASA.</p><p>Clinical, echocardiographic, angiographic and procedural characteristics were analysed in 113 consecutive patients. Successful ASA was defined as NYHA a parts per thousand currency signaEuro parts per thousand 2 with improvement of at least 1 class combined with a resting gradient <30 mmHg and provoked gradient <50 mmHg at 4-month follow-up.</p><p>In 37 patients ASA was not successful. In multivariate analysis, baseline gradient (OR 1.06 (1.01-1.11) per 5 mmHg, p = 0.024) and distance to the ablated septal branch (OR 1.09 (1.03-1.16) per mm, p = 0.004) were predictors of unsuccessful outcome. The combined presence of a non-ablated septal branch and a distance a parts per thousand yenaEuro parts per thousand 19 mm to the ablated branch was a predictor of unsuccessful outcome (OR 5.88 (2.06-16.7), p <0.001).</p><p>Baseline gradient and a greater distance from the origin of the left anterior descending artery to the ablated septal branch combined with a non-ablated proximal septal branch are associated with an unsuccessful outcome after ASA.</p>
