Echo Doppler
100
A patient undergoes echocardiographic assessment to quantify mitral regurgitation using the quantitative Doppler method. The following measurements are obtained:
- Aortic annulus diameter = 2.3 cm
- Aortic annulus Time Velocity Integral (TVI) = 17 cm
- Mitral annulus diameter = 4.3 cm
- Mitral annulus Time Velocity Integral (TVI) = 15 cm
Using these values, calculate the regurgitant volume (mL/beat) for this patient.
