37. Echocardiography Flashcards
1
Q
What is temporal resolution
A
Related to motion with respect to time
2
Q
M mode in cardiac US
A
Motion
3
Q
Grade 3 diastolic dysfunction charac
A
decrease LV, increase LVEDP
Elevated peak E, E/A > 2
4
Q
absolute contraindication to performing TEE
A
Esophageal pathology – diverticulum, laceration, stricture, tumor
GI blood is active
After esophagectomy Perforation of viscus
5
Q
Echo US waves
A
2-12 MHz
6
Q
E/A and diastolic dysfunction
Normal value e’
A
< 1 grade 1
> 2 grade 3
Lateral velocity of 10 or more excludes diastolic dysfunction
7
Q
Bernoulli equation in cardiac US
A
for estimating the severity of the stenosis
8
Q
Shape in LVOT
A
Dagger shape
9
Q
e’ in diastolic dysfunction
A
If e’ (lateral velocity) more than 10 there is no diastolic dysfunction
10
Q
When we can see pulmonary vein systolic flow reversal
A
MR
