Diastolic function : Mitral Inflow
 Key Points
1. PW Doppler is performed in the apical 4-chamber view to obtain mitral inflow
velocities to assess LV filling.
2. a 1-mm to 3-mm sample volume is placed between the mitral leaflet
tips during diastole to record a crisp velocity profile.
3.Primary measurements include peak E and A velocities, E/A ratio, DT, and IVRT
4.Mitral inflow patterns include normal, impaired LV relaxation, Pseudonormal
flow, and restrictive LV filling.
5.In patients with dilated cardiomyopathies, filling patterns correlate better
with filling pressures, functional class, and prognosis than LV EF.
6.In patients with coronary artery disease and those with hypertrophic cardio
myopathy in whom the LV EFs are 50%, mitral velocities correlate poorly wi
th hemodynamics.

Echocardiographic evaluation

• Echocardiographic evaluation of cardiac adaptation to the volume overload


offers, along with careful assessment of symptoms, and ideal tool for manag
ement of valvular regurgitation and timing of surgery

• 2D echocardiography provides an assessment of valvular structure,


mechanism of regurgitation and adaptation to the volume overload state

• Doppler has become the first line approach to the evaluation and management
of valvular heart disease

• Doppler allows a comprehensive evaluation of the severity of regurgitation

Calculation: Pulmonary Artery Pressure

• Mean PA pr= 4 (Vpeak)2


• PA end-diastolic pressure
= 4 (VED)2 + RVEDP
= 4 (VED)2 + RA pressure
