Aortic Valve Stenosis Hemodynamics

When the aortic valve calcifies and its orifice narrows, the same stroke volume must accelerate through a smaller opening — and the pressure the left ventricle must generate rises with the square of that jet velocity. This simulation renders the left-ventricle-to-aorta flow path in 3D, with a physically modeled valve orifice whose leaflets close in as you shrink the aortic valve area. Live flow particles trace the continuity equation in real time — thinning out and speeding up through the stenotic orifice — while the control panel applies the exact continuity and simplified Bernoulli equations echocardiographers use to grade aortic stenosis: adjust valve area, LVOT diameter, stroke volume and heart rate, and watch jet velocity, peak/mean transvalvular gradient and clinical severity update instantly.
