A non-compliant LV refers to a __________ LV.

flexible

stiff

impaired

strong

slow

stiff

All the following parameters are used to evaluate LV Diastolic function, Except:

IVRT

MV E:A

MV Deceleration Time

MV E point

Left atrial volume index

MV E point

(T/F) The normal E:A ratio is 1.0-1.5 in the book and 0.8 on the power point.

True

T/F: The MV E wave represents the early diastolic LA-LV pressure gradient (PG).

True

The mitral valve inflow provides critical information pertaining to diastolic function which includes all the following, except:

E wave duration

E:e' ratio (not this one)

E:A ratio

E wave deceleration time (not this one)

E:A ratio

A mitral valve deceleration time >240ms is __________ and represents ____________.

normal/normal relaxation/filling/stiffness

decreased/ reduced LV relaxation/filling/stiffness

increased/ reduced LV relaxation/filling/stiffness

increased/ reduced LV relaxation/filling/stiffness

T/F: Tissue Doppler imaging of the mitral annular motion measures the velocity of myocardial movement towards the PWD cursor as it passes through the sample gate.

True

T/F: E:E' > 14 indicates increased LV filling pressures.

True
