ARDMS Echo Hemodynamic Assessment

Question 1

Which echocardiographic parameter non-invasively estimates pulmonary capillary wedge pressure (PCWP)?

Accepted Answer

E/e' ratio (mitral E / tissue Doppler e')

Answer

Mitral A wave velocity

Answer

Tricuspid annular velocity

Answer

RVOT acceleration time

Question 2

The inferior vena cava (IVC) collapses less than 50% with sniff in a patient with a dilated IVC (>2.1 cm). What RAP estimate does this suggest?

Accepted Answer

≥15 mmHg

Answer

0–5 mmHg

Answer

5–10 mmHg

Answer

10–15 mmHg

Question 3

Which finding on M-mode or 2D echo suggests elevated left ventricular end-diastolic pressure (LVEDP)?

Accepted Answer

Tall mitral E wave with short deceleration time and B-bump on M-mode mitral valve

Answer

Low E/A ratio with prolonged IVRT

Answer

Dilated IVC with plethora

Answer

Increased TAPSE

Question 4

Stroke volume (SV) using echocardiography is calculated as:

Accepted Answer

LVOT VTI × LVOT cross-sectional area

Answer

LVOT VTI / LVOT diameter

Answer

LVOT diameter × peak LVOT velocity

Answer

LVOT VTI × heart rate

Question 5

A patient has a TR peak velocity of 3.5 m/s and estimated RAP of 10 mmHg. What is the estimated RVSP?

Accepted Answer

59 mmHg

Answer

39 mmHg

Answer

49 mmHg

Answer

69 mmHg

Question 6

Which finding indicates equalization of diastolic pressures across the pericardium in constrictive pericarditis?

Accepted Answer

Exaggerated respiratory variation in mitral inflow with septal bounce and dilated IVC

Answer

Uniform diastolic filling without respiratory variation

Answer

Reduced E/e' ratio with normal IVC

Answer

Systolic flow reversal in pulmonary veins alone
