文摘
- •
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.
