Using the color Doppler, it is possible to assess the degree of mitral regurgitation by the regurgitation area, and its percentage ratio with the area of the left atrium.

 

jet area

Jet are has to be measured in Color doppler mode using apical positions (Trasing around regurgitation jet).

Grading the severity of chronic mitral regurgitation by jet area:

• Mild - Small, central, narrow, often brief (usually < 4 cm2).
• Moderate - Variable.
• Severe - Large central jet (usually > 10 cm2) or eccentric wall-impinging jet of variable size

 

jet area/LA area ratio

Jet are has to be measured in Color doppler mode using apical positions (Trasing around regurgitation jet). The Left Atrium area has to be measured in the same echocardiography view.

Grading the severity of chronic mitral regurgitation by jet area/LA area ratio:

• Mild - Small, central, narrow, often brief (usually < 20% of LA area).
• Moderate - Variable.
• Severe - Large central jet (>50% of LA) or eccentric wall-impinging jet of variable size.
