Question 1

In echocardiography, the parasternal long axis view best assesses:

Accepted Answer

Mitral valve, aortic valve, left ventricle, and aortic root

Answer

The parasternal long axis (PLAX) view provides excellent visualization of the mitral valve, aortic valve, left ventricle, and aortic root.

Question 2

Doppler echocardiography measures:

Accepted Answer

Blood flow velocity and direction

Answer

Doppler echocardiography uses the Doppler effect to measure blood flow velocities and directions within the heart and great vessels.

Question 3

A stress echocardiogram is used primarily to detect:

Accepted Answer

Inducible myocardial ischemia

Answer

Stress echocardiography identifies regions of inducible ischemia by comparing wall motion at rest versus stress (exercise or pharmacologic).

Question 4

Transesophageal echocardiography (TEE) is preferred over transthoracic echocardiography (TTE) for evaluating:

Accepted Answer

Left atrial thrombus and aortic dissection

Answer

TEE provides superior image quality for posterior structures like the left atrial appendage and descending aorta, making it ideal for detecting thrombus and aortic dissection.

Question 5

Color flow Doppler in echocardiography encodes blood flow direction as:

Accepted Answer

Red = toward transducer, Blue = away from transducer

Answer

By convention (BART), red indicates flow toward the transducer and blue indicates flow away from the transducer in color Doppler imaging.
