Comparison of mean transvalvular pressure gradients measured by TTE versus by CMR. Panel A shows the Pearson correlation plot for mean transvalvular pressure gradient measured by TTE (MPG_TTE) and CMR (MPG_CMR). Panel B shows the corresponding Bland-Altman plot. Panel C shows the Pearson correlation plot for mean transvalvular pressure gradient measured by TTE (MPG_TTE) and predicted by Gorlin equation using CMR (MPG_CMR-Gorlin). Panel D shows the corresponding Bland-Altman plot. Panel E shows the Pearson correlation plot for mean transvalvular pressure gradient measured by TTE (MPG_TTE) and predicted model using vorticity and dimensionless stroke volume from CMR (MPG_{CMR-Predicted}). Panel F shows the corresponding Bland-Altman plot.
