Introduction Aortic stenosis (AS) is a significant health problem, particularly in older individuals, most common valve disease necessitating surgical or percutaneous intervention. Echocardiography central diagnosis, management assessment progression AS patients. severity grading based on 3 parameters: aortic area by continuity equation (AVA), mean gradient (MG), peak velocity (Vmax). Although AVA relevant low situations, its calculation more complex therefore may show greater technical variability. Knowing differences between parameters to assess be useful clinical practice. Purpose Assess main quantitative detect patients with AS. Methods We retrospectively analyzed cohort 130 diagnosis isolated (without other disease) 2 echocardiograms performed at an interval than 1 year, which calculated using was measured. The annual rate change AVA, MG, Vmax, proportion predefined criteria (AVA decrease >0.2 cm2, MG increase > 10 mmHg, Vmax 30 cm/s) were analyzed. Results 26 (9) months. Globally, small for parameters, higher considering (49.2%), lower (28.5%), being intermediate (36.1%) (Table). Of 47 criteria, observed 32 (68%), only 19 (40%) criteria. Conclusions criterion considered practice guidelines, many it not associated changes MG. Discrepancies across different frequent lead inconsistent decision making.
