Vena contracta width may simplify MR severity grading; hypothesis-generating and should not yet change practice.
Does vena contracta width by Doppler color flow mapping accurately predict the severity of mitral regurgitation in patients with MR?
Vena contracta width measured by Doppler color flow mapping provides a simple and accurate quantitative assessment of mitral regurgitation severity.
