RAP = 8 mmHg
TR velocity = 3.4 m/sec

Answer 1

54 mmHg

Question 2

Calculate the E/e prime ratio given the following numbers

E wave peak velocity = 1.15 m/s
e prime peak velocity = 16 cm/s

Answer 2

7.2

Question 3

Calculate the E/e prime ratio given the following numbers

E wave peak velocity = 1.15 m/s
e prime peak velocity = 16 cm/s

Answer 3

7.2

Question 4

Which of the following statements are true regarding TV CW Doppler?

1. The baseline should be set 1/3- 1/4 from the bottom
2. The signal should be adjusted to the flow visualized
3. The signal should be adjusted to visualize potential regurgitation
4. The signal is not routinely optimized for the inflow because tricuspid stenosis in the adult population is rare

Answer 4

1. The baseline should be set 1/3 to 1/4 from the bottom
2. The signal should be adjusted to visualize potential regurgitation

Question 5

Which is true regarding the measurement seen in the image below?

1. This measurement has accurately been taken at the peak broadest spectral signal
2. This measurement has accurately been taken at the peak modal velocity
3. This measurement has inaccurately been taken at the peak modal velocity
4. This measurement has inaccurately been taken at the peak broadest spectral signal

Answer 5

This measurement has accurately been taken at the peak modal velocity

Question 6

On today’s exam, a sonographer obtains a RVSP of 64 mmHg, but on the same patient’s echo 2 days ago the RVSP was measured at 55 mmHg.

One reason for discrepancy was that the pressure actually increased in the interval between exams.

What is the other most likely reason for discrepancy?

Answer 6

The doppler angle on today’s study was better aligned to the regurgitant jet.
