Test 3

CVT-246-01 - Non-Invasive Cardiology Special Topics

QuestionAnswer
What views are required to obtain radial and circumferential strain? Parasternal short axis basal, mid, and apex
What is myocardial dyssynchrony testing used for? used to evaluate dual chamber pacer therapy
What is the normal value for global longitudinal strain? -20 to -23
List at least three clinical applications for global longitudinal strain. evaluation of systolic and diastolic function, early detection of chemo-induced cardiotoxicity, ischemic heart disease, coronary artery disease, takotsubu evaluation of HOCM and amyloidosis PHTN
Why are volume measurements more accurate during a three-dimensional echo? foreshortening that may occur in 2d is not a factor in 3d imaging thus making 3d more reliable
Which of the following types of strain imaging is used most in the clinical environment? Global longitudinal
What views are required to obtain global longitudinal strain? Apical 2, 3, 4
Which of the following is more sensitive to myocardial changes? Global longitudinal strain TDI at the mitral annulus measure S' Left ventricular ejection fraction Left ventricular fractional shortening Global longitudinal strain
List at least three applications for three-dimensional echocardiography. evaluation of left ventricular volume and function evaluate valve structures evaluate septal defects
What does ICE stand for? intracardiac echocardiography
What is the normal value for radial strain? 50 – 70
What does longitudinal strain measure? The positive and negative strain from base to apex
All of the following can be used during myocardial dyssynchrony testing except: Tissue Doppler M-Mode imaging Pulsed wave Doppler Two-dimensional imaging M-Mode imaging
List three clinical applications for ICE. used to guide septal defect closures used during valvotomy or valve replacements used during ablation monitoring
List at least three techniques to optimize the image when using global longitudinal strain. on axis apical imaging, no foreshortening acquire 3 loops at end-expiration, must visualize the endocardium narrow sector width, shallow depth, frame rate 50 to 90
What is the normal value for strain rate? 1 to 1.4
True or False Positive strain rate is when two points of a speckle move closer together during systole. False

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
