Figure 3

Effective orifice area and mean transvalvular pressure gradients. Panel A shows the aortic valve effective orifice area and mean transvalvular pressure gradient (MPG) plot using measurements from TTE (MPG_TTE) and CMR (MPG_CMR). Panel B shows the same plot but using MPG predicted by Gorlin equation and CMR measurements (MPG_CMR-Gorlin). Panel C shows the same plot but using MPG predicted using mean vorticity magnitude and dimensionless stroke volume from CMR measurements (MPG_{CMR-Predicted}).
