Abstract
<p><strong>Introduction:</strong> The aortic-septal angle (ASA) decrease, throughout the deformation of the left ventricle secondary to the aorta stretching, is usually associated to aging. Nonetheless, the importance of ASA measurement remains unclear in patients with degenerative aortic stenosis (AS).</p> <p> </p> <p><strong>Purpose</strong>: To evaluate the ASA in patients with moderate to severe AS (group A) and to compare it to a hypertensive group (group B), as well as with a control group (group C). To determine the prognostic value of ASA regarding heart failure admissions in P with AS.</p> <p> </p> <p><strong>Methods:</strong> There where included 45 patients (P) in the group A, 45 in group B and 23 in group C. Transthoracic echocardiogram was performed in all P. The ASA was measured through the evaluation of the angle between the left ventricle (LV) cavity and the outflow tract, in parasternal long-axis view, in systole and diastole. A clinical follow-up was made regarding heart failure admissions.</p> <p> </p> <p><strong>Results:</strong> One hundred and thirteen P, 57% male, with a mean age of 72±11 year old were studied. In Group A the valvular aortic area was 0,43±0,15 cm<sup>2</sup>/m<sup>2</sup>, and the LV ejection fraction was (LVEF) 60±14%. Group A P had a ASA reduction, when compared with Group B and C, both in systole (109±4 vs 124±3º vs 118±3º, <em>P</em><0.01) and in diastole (107±3º vs 124±4º vs 117±3º, <em>P</em><0.01). There was a significant negative correlation between ASA and age; and a positive correlation between diastolic ASA and arterial pressure (systole <em>r</em>=-0,3, <em>p</em>=0.02; diastole, <em>r</em>=-0.3, <em>P</em>=0.01). There were not found significant correlations between ASA and gender, body mass index or vascular and valvular components in Groups A and B. However, there was a significant correlation between systolic ASA and LV mass index (<em>r</em>=-0,31, <em>P</em>=0.01) and LV shortening fraction (<em>r</em>=0,36, <em>P</em><0.02). During clinical follow-up (972±94 days), P with AS admitted for acute heart failure had lower systolic and diastolic angles (P<0.01).</p> <p> </p> <p><strong>Conclusion:</strong> According to our data, we conclude that ASA can be used as a marker for arterial-ventricular remodeling, a characteristic feature of aortic stenosis, and a predictor of heart failure admissions in P with AS. </p>
