Web17 sept. 2024 · A normal sized aorta has a valve area of approximately 3.0cm2 (3.0 centimeters squared) and 4.0cm2. Normal aortic velocity would be greater than 3.0m/sec (3.0 meters per second), while a normal mean pressure gradient would be from zero to 20mm Hg (20 millimeters of mercury, which is how blood pressure is measured). WebIntroduction. Aortic stenosis (AS) and hypertrophic cardiomyopathy (HCM) are two conditions that can cause hemodynamic gradients in the left ventricular outflow tract (LVOT). 1 In both cases the presence of significant obstruction has clinical, therapeutic and prognostic implications. 1–3 The presence of both of these conditions in the same patient …
