Echo URR Exam Questions and
Answers |100% Pass
You identify a PFO on an echo and the cardiologist asks you to calculate the LAP. How
will you perform this calculation? - Answer-Measure the peak velocity across the
PFO, calculate the peak pressure gradient across the defect and add the RAP.

Which of the following correctly describes how AS is evaluated by catheterization?
A) the catheter is placed at the AV to assess the peak pressure gradient
B) Doppler ultrasound is used to assess the flow velocity in the LVOT and at the AV
C) the catheter is placed in the LV and then advanced through the AV to assess the
pressure difference
D) the intracoronary transducer is inserted into the aorta to assess the peak pressure -
Answer✔✔-C)
Which of the following correctly describes how to measure the acceleration time of the
PV waveform?
A) measure the time from onset of sys to the systolic peak
B) trace the waveform from start to finish
C) measure the slope of the line from the onset of systole to the systolic peak
D) measure the distance from the onset of sys to the systolic peak - Answer✔✔-A)
When is imaging performed during a stress echo using a supine exercise bike?
A) within 30 sec after the cessation of exercise
B) within 60 sec after the cessation of exercise
C) during peak exercise
D) when the HR increases by 50% from the rest - Answer✔✔-C) bc the supine
exercise bike is normally used for valvular assessment, imaging is performed at peak
exercise to obtain the peak velocity
