QUESTION 1
Which of the following techniques can be used to most accurately differentiate a
left sided cardiac mass from a sonographic artifact?
Use multiple views and planes to evaluate the area.
Use microbubbles to delineate the chamber walls.
Switch to a higher frequency transducer.
Adjust compression, gain and add B color to enhance the image. - ANSWERS-
Use microbubbles to delineate the chamber walls.
All of the above choices are techniques used to assess the presence/absence of a
mass versus an artifact but the most accurate would be the use of contrast to
delineate the walls of the chamber. Thrombus forms adjacent to the ventricular

walls with abnormal motion and due to stasis in the left atrium. Optison, Levovist
and Definity are examples of microbubble contrast agents used in echo to evaluate
wall motion and thrombus formation.
QUESTION 2
. ______________________ is the preferred method of diagnosis of constrictive
pericarditis.
Cardiac catheterization
Echocardiography
CT
MRI - ANSWERS-Cardiac catheterization is the preferred method of diagnosis of
constrictive pericarditis.

thickened AV leaflets
left ventricular hypertrophy
left ventricular enlargement - ANSWERS-right ventricular enlargement
QUESTION 4
What is the best way to correct the color Doppler artifact ?
decrease rejection
increase the color velocity scale
decrease the Doppler gain
increase color threshold - ANSWERS-decrease the Doppler gain

EXAM
Which of the following correctly describes the mitral valve Doppler tracing of a
patient with hypertrophic cardiomyopathy?
E/A ratio <0.8
E/A ratio >2.0
varies with systemic blood pressure
E/A ratio 1.0 - ANSWERS-E/A ratio <0.8
HCM causes a stiffer left ventricle with abnormal relaxation that causes a short E
wave and tall A wave. (E/A ratio <0.8)
QUESTION 6
