Chapter 4 Part 4 Images

This is a way to find out if the patient has MS or MR, and is also used to calculate the MVA, mean PG and pressure half-time if MS is present.

• CWD

• PWD

This gives us a sample of inflow at the tips of the MV leaflets and is used for the diastolic function assessment.

• CWD

• PWD

This is a mode of echo that measures the velocity of the heart muscle through the phases of one or more heartbeats by the Doppler effect of the reflected ultrasound

• CWD

• PWD

• Tissue Doppler (TDI)

The chambers will affect the velocity and shape of the Doppler inflow signal. This is a relationship between early and late filing, how rapid flow velocity declines in early diastole, and how long it takes for filling of the ventricle to start after the ventricle relaxes.

• CWD

• PWD

• Tissue Doppler to assess diastolic function and dysfunction

• TDI

This is to evaluate pulmonary vein flow reversal and the hemodynamics due to MR.
