Blood velocity at end of diastole on Doppler ultrasound
Expansion
End-Diastolic Velocity
Purpose
Contributes to resistive index calculation and stenosis grading
Clinical Context
End diastolic velocity reflects diastolic flow. Elevated end diastolic velocity (with high peak systolic velocity) indicates severe stenosis with persistently elevated flow during diastole.
Related Terms
- PSV
- Doppler ultrasound
Key Points
- Elevated end diastolic velocity with elevated peak systolic velocity indicates significant stenosis
