Determination of vena contracta and its value in evaluating severity of aortic regurgitation.

The Journal of heart valve disease, 2003
Recent studies evaluating the severity of valvular insufficiencies have focused on the effective regurgitant orifice area (EROA), which corresponds hydrodynamically to the cross-sectional area of the vena contracta (VC). The study aim was to quantify aortic regurgitation (AR) by using color Doppler imaging of the VC.Fifty-five patients with chronic AR ...
