Key result
A regurgitant jet diameter of ≥5.5 mm measured by transesophageal Doppler identified severe mitral regurgitation with 92% sensitivity and 92% specificity.

p-value: p=<0.001
Measuring the regurgitant jet width at its origin using transesophageal Doppler color flow imaging provides a simple and highly accurate method for assessing the severity of mitral regurgitation.
Tribouilloy et al. (1992) conducted a cross-sectional in mitral regurgitation (n=63). Transesophageal Doppler color flow imaging vs. Cardiac catheterization (angiographic grading) was evaluated on Correlation between jet diameter at its origin and angiographic grade of mitral regurgitation (r = 0.86, p=<0.001). A regurgitant jet diameter of ≥5.5 mm measured by transesophageal Doppler identified severe mitral regurgitation with 92% sensitivity and 92% specificity.
