The authors assessed correction of Doppler gradients for pressure recovery in aortic stenosis.
Uncorrected and corrected Doppler gradients correlated similarly with catheterization gradients.
Corrected Doppler gradients had significantly better agreement with catheterization gradients.
Corrected Doppler gradients better predicted catheterization gradients above various thresholds.
Correcting for pressure recovery may optimize the use of catheterization.
