Key result
Live 3D TTE measurements of vena contracta area correlated better with aortographic or surgical grading of aortic regurgitation (r = 0.95) than 2D TTE measurements of vena contracta width (r = 0.92).
Why the study?
Does live 3D TTE measurement of vena contracta area improve the accuracy of aortic regurgitation assessment compared to 2D TTE when validated against aortography or surgery in adult patients?
Observational (n=56)

Effect estimate: r = 0.95
Live 3D TTE measurement of vena contracta area provides highly accurate assessment of aortic regurgitation severity, correlating better with invasive reference standards than standard 2D TTE.

May aid aortic regurgitation grading; extends mitral regurgitation 3D vena contracta work but remains hypothesis-generating.
Fang et al. (2005) conducted an observational in Aortic regurgitation (n=56). Live 3D TTE measurements of vena contracta area vs. 2D TTE measurements of vena contracta width and aortography/surgery was evaluated on Correlation with aortographic or surgical grading of aortic regurgitation (r = 0.95). Live 3D TTE measurements of vena contracta area correlated better with aortographic or surgical grading of aortic regurgitation (r = 0.95) than 2D TTE measurements of vena contracta width (r = 0.92).
