The right heart catheterization waveform in the figure that represents pressure in the right ventri-cle is which of the following?
 
  a. A c. C
  b. B d. D

Question 2

Pulmonary artery occlusion pressure can be used to estimate:
 
  a. left-atrial preload.
  b. left-atrial afterload.
  c. left-ventricular end-diastolic pressure.
  d. right-ventricular end-diastolic pressure.

Answer to Question 1

ANS: B
The pressure tracing from a right heart catheterization will first show the right atrial pressure tracing, followed by the right ventricle.

Answer to Question 2

ANS: C
Pulmonary artery wedge pressure, or pulmonary artery occlusion pressure, is used as an estimate of left atrial pressure and thus preload of the left ventricle, or left-ventricular end-diastolic pres-sure.
