The maximal pressure gradient … WebIt is calculated as the ratio of the subvalvular velocity obtained by PW Doppler and the maximum velocity obtained by CW Doppler across the prosthetic valve. This peak velocity ratio is dimensionless and does not rely on determination of cross-sectional area of the LVO thus making it less dependent on valve size and especially useful when the ...
