Flashcards in Echocardiology Deck (32):
1

advantages of echo

non-invasive, real-time imaging of beating heart

anatomic detail can be accurately visualized

cardiac measurements - assess size and function

grading of Dz

evaluate therapy

interventional steps 

2

disadvantage to echo

a diagnosis of cardiac failure cannot be base on echo alone

3

transducer used for large dogs

sector transducer

3.0 -5.0 MHz

 

4

transducer used for small dogs

sector transducer

5.0 - 7.5 MHz

5

transducer used for cats

sector transducer

7.5 -10 MHz

6

T/F it is possible to diagnose complex CV disease with echo

True

but it takes practice

7

T/F in order to keep the patient quiet and still you may have to sedate them during the procedure

False

avoid sedation due to cardiovascular changes

8

echo ususally begin in _________ recumabancy 

right lateral 

9

B- mode

real-time tomographic views

anatomic information - masses, valve abnormalities, pericardial effusion, septal defects, global cardiac function and size

10

what is M-mode used to for

measurement of: wall thickness, chamber size, fractional shortening, valve movement pattern 

11

T/F only structures associated with the cursor will be scanned in B-mode

False

only structures associated with the cursor will be scanned in M-mode

12

this image was obtained using which mode 

B- mode

13

this image was obtained using which mode

M-mode

14

doppler can be used to detech:

normal and abnormal blood flow through the heart

insufficiencies and stenosis

aquired cardiac disease

15

according the the dopler principle, blood flow must be _______ to the ultrasound beam 

parallel 

16

spectral doppler

velocity and direction along y-axis

time alon x-axis

17

"below baseline" = 

away from transducer

18

doppler measurements are obtained from patient in __________recumbency

left lateral recumbency

19

turbulent flow (reguritation) appears as ______on doppler

bright, mixture of colors

20

describe the change seen here

aortic insufficiency

jet from aorta back to the LV 

21

name the view

right parasternal long axis view

22

Name the structure labeled A

Aorta

Mercedes Benz sign

23

name the structure labeled B

Left Atrium 

24

name the structure seen here

Left Ventricle

mushroom 

25

name the structure seen here

Mitral valve

fish mouth

26

this imaged was obtained using which mode

M-mode

27

T/F this is a properly obtained image using M-mode

False

dont do this

28

EDD = 

maximal diastolic left ventricular interior diameter

29

ESD = 

end systolic ventricular interior diameter

30

how is % fractional shortening calculated

%FS = (EDD - ESD)/EDD x 100

31

normal range of fractional shortening in dogs

28 - 45%

32

normal range of fractional shortening in cats

44 - 45%
