CIR CIR Hemodynamic Monitoring & Cardiac Catheterization 2

Question 1

During coronary angiography, the Judkins right catheter is most commonly used to cannulate which ostium?

Accepted Answer

Right coronary ostium

Answer

The Judkins right (JR4) catheter is specifically shaped to engage the right coronary artery ostium from the right femoral or radial approach.

Question 2

What does an 'A' wave on a central venous pressure (CVP) tracing represent?

Accepted Answer

Atrial contraction

Answer

The 'A' wave on CVP tracing corresponds to atrial contraction against a closed or closing tricuspid valve.

Question 3

Which finding on hemodynamic tracings is characteristic of cardiac tamponade?

Accepted Answer

Equalization of diastolic pressures across chambers

Answer

Tamponade physiology produces equalization of RA, RV diastolic, PA diastolic, and PCWP pressures due to pericardial compression.

Question 4

A thermodilution cardiac output measurement involves injection of cold saline into the:

Accepted Answer

Right atrium

Answer

Cold saline is injected into the right atrium through the proximal port of a Swan-Ganz catheter, and temperature change is detected distally in the pulmonary artery.

Question 5

Elevated left ventricular end-diastolic pressure (LVEDP) above 18 mmHg most likely indicates:

Accepted Answer

Left ventricular dysfunction or failure

Answer

LVEDP > 18 mmHg reflects impaired LV compliance or systolic dysfunction, indicating elevated filling pressures consistent with heart failure.
