Echocardiography can measure what 3 things?

• A. Ejection Fraction
• B. Stroke Volume
• C. Valve Leaf Motion with in the heart
• D. All of the above

Answer: (D)

Echocardiography provides both structural and functional insight into the heart, so you can assess how effectively the ventricle pumps, how much blood fills and leaves the heart, and how the heart valves move. Ejection fraction is a go-to measure of systolic function, calculated from the LV end-diastolic and end-systolic volumes obtained with 2D or 3D imaging (often using the Simpsons method). Stroke volume is the amount of blood ejected with each beat and can be determined from the difference between EDV and ESV, or estimated from Doppler measurements of flow across the outflow tract (area of the valve opening times the velocity-time integral). Valve leaf motion is visualized directly with 2D and M-mode imaging, and Doppler assesses how the leaflets move and the resulting regurgitation or stenosis. Since echo can provide all three types of information, the best answer is that all of these can be measured.
