GRADE 0:
                              ABSENT







                              GRADE 1:
                              MINIMAL









                              GRADE 2:
                              BLUNTED







                              GRADE 3:
                              DAMPENED






                                                  - MFV of >80 cm/s AND velocity difference >30%
                                                  compared to control side or
                              GRADE 4:            - if both affected and comparison sides have MFV
                              STENOTIC            <80 cm/s due to low end-diastolic velocities, MFV
                                                  >30% compared to the control side AND signs of
                                                  turbulence.





                              GRADE 5:           - >30% mean velocity difference compared to control
                              NORMAL             - Similar waveform shapes compared to control
