CET Echocardiogram Interpretation & Diagnostics

Question 1

What does an echocardiogram primarily assess?

Accepted Answer

Heart structure and function

Answer

An echocardiogram uses ultrasound waves to create real-time images of the heart. It provides detailed information about the size, shape, and movement of the heart chambers, valves, and major blood vessels. This allows for comprehensive assessment of cardiac function, such as pumping efficiency, valve integrity, and the presence of structural abnormalities.

Question 2

What does left ventricular ejection fraction (LVEF) indicate?

Accepted Answer

Pumping efficiency of the heart

Answer

Left Ventricular Ejection Fraction (LVEF) is a crucial measurement that quantifies the percentage of blood pumped out of the left ventricle with each heartbeat. It is a key indicator of the heart's overall pumping ability and is widely used to diagnose and monitor conditions like heart failure. A healthy LVEF typically ranges from 50-70%.

Question 3

What might turbulent flow on Doppler imaging suggest?

Accepted Answer

Valve dysfunction

Answer

Turbulent blood flow, detected by Doppler imaging, indicates an abnormal, chaotic flow pattern rather than smooth, laminar flow. This often suggests an obstruction or regurgitation through a heart valve, such as stenosis (narrowing) or insufficiency (leakage). Therefore, turbulent flow is a strong indicator of valve dysfunction, requiring further investigation.

Question 4

Which view is best for visualizing the mitral valve?

Accepted Answer

Parasternal long axis

Answer

The parasternal long axis (PSLA) view is a fundamental echocardiographic window that provides an excellent visualization of the left ventricle, left atrium, aortic root, and both the mitral and aortic valves. This view allows for clear assessment of mitral valve leaflets, their motion, and any potential abnormalities, making it ideal for evaluating this structure.

Question 5

What does a pericardial effusion appear as on echo?

Accepted Answer

Dark fluid area

Answer

Pericardial effusion is the accumulation of fluid in the pericardial sac surrounding the heart. On an echocardiogram, fluid appears anechoic (dark) because ultrasound waves pass through it without significant reflection. This dark, fluid-filled space can be seen separating the pericardium from the epicardium, indicating the presence of an effusion.
