Aortic Valve Stenosis: Doppler Waveform & Planimetry (2D)

2D real-time Doppler velocity-time tracing and en-face planimetry view of a stenotic aortic valve: a time-resolved pulsatile flow model drives the continuity equation and simplified Bernoulli equation, live, exactly as continuous-wave Doppler echocardiography does.

The same continuity-equation and simplified-Bernoulli physics as the 3D duct model, re-derived here as a genuinely time-resolved pulsatile flow — a half-sine ejection waveform whose peak is solved so its time integral exactly matches your chosen stroke volume — drawn the way a real echocardiogram actually displays it: a live scrolling Doppler velocity-time tracing (LVOT vs. jet velocity) and a shaded instantaneous pressure-gradient curve whose area gives a genuinely measured mean gradient, alongside an en-face planimetry view of the valve orifice sized to true area. Adjust valve area, LVOT diameter, stroke volume and heart rate and watch both waveforms reshape live.

⚙ Under the hood

A 2D real-time continuous-wave Doppler velocity-time tracing and en-face planimetry view of a stenotic aortic valve, driven by a genuinely time-resolved pulsatile flow model (a half-sine ejection waveform whose peak is solved so its time-integral exactly equals stroke volume) through the same continuity equation and simplified Bernoulli equation echocardiography uses, with a measured (numerically time-integrated) mean gradient rather than a fixed clinical rule-of-thumb.
