RV Diastolic Exam Components

Question 1

Hepatic Vein Flow

Answer 1

1. Changes in S, D and Ar waves

S -
D -
Ar +

(Severe tricuspid regurge = S+ wave and blunted)

Question 2

TV Flow components
and
What are you ruling out?

Answer 2

1. Profile (is the E and A wave normal?)
2. E/A ratio
3. Decel time
4. Rule out tricuspid regurge
5. VTI (peak and mean velocities and gradients)

Question 3

Tissue Doppler components
and
What are you checking for with TDI?

Answer 3

1. E’ & A’

2. make sure there is no reversal

Question 4

Filling Pressures

Answer 4

make sure they are within normal range

Question 5

Right Heart volumes

Answer 5

make sure they are within normal range

Question 6

RV systolic performance

Answer 6

make sure it is normal

Question 7

How do you rule out PHTN using TR jet velocity and RAP?

Answer 7

4 ( VmaxTR) ^2 + RAP

Question 8

What are the Normal, Mild, Moderate and Severe values for PHTN?

Answer 8

N: 18 - 25
Mild: 30 - 40
Moderate: 40 - 70
Severe: > 70
