TTE Part 5 Workbook questions

According to the ASE, left ventricular diastolic dysfunction is usually the result of ___

• decreased pressure and volume

• impaired function and increased size

• impaired LVEF and filling

• impaired relaxation and increased chamber stiffness

True or False

Left ventricular diastolic function evaluation is vital in patients with potential diastolic dysfunction and the results should be included in the report, particularly those with dyspnea or heart failure

• True

• False

Choose a known diastolic function parameter.

• CWD of the mitral inflow

• CWD of the pulmonary venous inflow

• left atrial linear dimension

• tissue Doppler imaging (TDI) of the mitral annulus

What critical information does the mitral inflow PWD provide as it pertains to diastolic function?

• A-wave deceleration time

• E-wave duration

• E-wave peak velocity

• e'-wave peak velocity

Which statement supports the mitral inflow E-wave deceleration time?

• affected by left ventricular relaxation, diastolic pressure and stiffness

• must return to baseline during acquisition because it is a measurement of time, not slope

• utilized to recognize the filling pattern (normal, impaired, pseudonormal, restrictive)

• All of the above

True or False

Doppler sweep speed should be decreased from 50 to 25 mm/s for the diastolic function parameters.

• True

• False

Choose the statement that best supports the mitral inflow E-wave peak velocity.

• Increase with age

• Is not affected by changes in left atrial pressure

• Is not affected by changes in left ventricular relaxation

• Represents the early diastolic left atrial-left ventricular PG

True or False

TDI of the mitral annulus measures the Doppler frequency shift of the moving myocardium

• True

• False

True or False

Normally, TDI of the mitral annulus is a mirror image of the mitral inflow PWD waveform.

• True

• False

Choose the statement that best describes the E/e' ratio.

• < 8 usually predicts normal left ventricular filling pressure

• < 14 indicates increased left ventricular filling pressure

• Normal range 13-15

• Shouldn't be a mirror image of the mitral valve
