Does 3D reconstruction of color Doppler flow maps accurately quantify the severity of aortic regurgitation compared to electromagnetic flowmeters in an animal model?
Effect estimate: r=0.99
3D reconstruction of color Doppler flow maps provides highly accurate quantification of aortic regurgitation severity in an animal model.
Mori et al. (1999) studied Aortic regurgitation (n=6). 3-dimensional (3D) reconstruction of color Doppler flow maps vs. Electromagnetic flowmeters and continuous-wave Doppler velocities was evaluated on Correlation between 3D-derived vena contracta areas and reference effective orifice areas (r=0.99). 3D reconstruction of color Doppler flow maps accurately quantified aortic regurgitation severity, showing excellent correlation with reference effective orifice areas (r=0.99).
