High Yield PTEeXAM Review Part 21-23

Question 1

What are who aspects that increase significance of pressure recovery?

Answer 1

1. Increased Aortic Stenosis severity

Question 2

When you are performing a cath-derived peak pressure, how does that comprae to doppler derived gradients?

Answer 2

Pressure Recovery

CWD > Cath

Cath derived are measured distl to areaa of “low” pressure yielding lower pressure graadients than the actual peaka

What is the doppler equation?

Answer 3

Change in F = V cos (angle) 2 Ft / C

Question 6

Does MPI (Myocardial Performance Index) a measure of systolic or diastolic function?

Answer 6

BOTH

Question 7

Is MPI (Myocardial Performance Index) load dependent?

Answer 7

NOT load dependent

Question 8

What is the MPI (Myocardial Performance Index) equation?

Answer 8

[IVRT + IVCT] /ET

Question 9

What TEE view do you need to obtain MPI (Myocardial Performance Index)?

Answer 9

TG Deep 5 chamber

Question 10

What is the answer to the photo?

Answer 10

B = Isovolumetric Contraction Time

Question 11

A RV MPI above WHAT was found to be predictive of hemodynamic instability and mortality afater cardiac valvular surgery?

Power Doppler

Question 14

What is the velocity of sound in units (mm/microsecond)?

Answer 14

1.54 mm / microsecond

1540 m/sec is other units

Question 15

How does the PWD shift if you move the cursor from the distal LA to the MV annulus?

1. Peak E wave change?
2. Deceleration time change?

Answer 15

1. Peak E wave increases
2. Deceleration time decreases

Question 18

What is the neck/aneurysm diameter of a pseudoanuerysm of the LV?

Answer 18

<0.5

Question 19

What is the neck/aneurysm diameter of a true aneurysm of the LV?

Answer 19

Neck/Aneurysm size >0.5

Question 20

What does the myocardial to aneurysm transition look like for aneurysm vs. pseudoaneurysm?

Answer 20

Aneurysm = Gradual transition

Pseudoaneurysm = Abrupt transition

Question 21

What does the angle between normal myocardium and aneurysm look like for aneurysm vs. pseudoaneurysm?

Answer 24

1 cycle = 1 microsecond

Question 25

For MHz (Mega Hz), how many cycles are in one second?

Answer 25
