Module 13.1 : Apical Color and Spectral Part 2 Flashcards
1
Q
right heart doppler in apical 4 chamber
A
- mostly of color and spectral doppler of tricuspid valve
- pulmonary valve is rarely seen due to its anterior position
- assess TV inflow as well as regurge
2
Q
assess amount of TR
A
- tricuspid regurge
- close to 80% have it
- important to differentiate between normal and abnormal regurge
3
Q
physiologic/trace/normal TR
A
- result of normal function of right heart combined with lower pressures
- TV closes later than MV
- seen during FIRST HALF OF SYSTOLE
4
Q
normal color doppler of TV
A
- look for blue mosaic color
- red is inflow
- blue is regurge
- color scale is sam as MV
+ 50-70 cm/s
5
Q
color doppler of significant or abnormal TR
A
- large color jet
- dilated RV and RA
- both atria dilated
- place cursor line in the middle of jet
6
Q
CW of tricuspid valve
A
- able to capture both inflow and regurge on same image
- inflow velocity will be small (NOT MEASURE)
- measure peak velocity and calculate RVSP
7
Q
RVSP equation
A
RVSP = 4(TR peak velocity)^2 + RAP
8
Q
RVSP AND PASP
A
- RVSP is equal to PASP only when no RV outflow obstruction is present
9
Q
PW TV inflow
A
- waves are same as PW of the mitral valve
- E wave should be greater than A wave
- no measurements taken here
10
Q
TV normal E wave
A
< 0.7 m/s
11
Q
TDI of TV annulus - S prime normal
A
- S prime wave should be > 9.5 cm/s
12
Q
apical 2 chamber doppler
A
- basic routine is to take two images
+ apical 2D cine
+ apical color MV - no spectral in this view
13
Q
apical long axis color assesses
A
- MV and AV
14
Q
apical long axis spectral asseses
A
- LVOT pulsed wae
- AV CW
+ if CW already done in A5C and is normal then don’t need to do tis
15
Q
PW of LVOT LAX
A
- trace LVOT VTI in either the A5C or A3C not in both views for normal hearts
