RCIS Cardiac Catheterization Techniques and Contrast Media 2

Question 1

The Judkins left 4 (JL4) catheter is designed to engage the left coronary ostium without active manipulation from which access site?

Accepted Answer

Femoral

Answer

The Judkins left 4 catheter is shaped to passively engage the left coronary ostium from the femoral approach without requiring active catheter manipulation.

Question 2

During coronary angiography, the LAO cranial (Spider) view is best used to visualize which coronary segment?

Accepted Answer

Mid and distal LAD with septal perforators and diagonal branches

Answer

The LAO cranial (Spider) view elongates the mid and distal LAD, separating septal perforators and diagonal branches for optimal visualization.

Question 3

What is the purpose of test injections before full contrast injection in selective coronary angiography?

Accepted Answer

To verify catheter position, exclude deep intubation or pressure damping, and confirm coaxial engagement

Answer

Small test injections confirm coaxial catheter seating, detect pressure damping from ostial disease, and ensure the catheter is not deeply intubated before a full injection.

Question 4

Pressure damping during coronary catheter engagement is most commonly caused by:

Accepted Answer

Ostial coronary stenosis or catheter tip occlusion of the vessel lumen

Answer

Pressure damping indicates catheter tip occlusion of the coronary lumen, often due to ostial stenosis or a catheter that is too large for the vessel.

Question 5

Fractional flow reserve (FFR) measurement requires which pharmacologic agent to induce maximal coronary hyperemia?

Accepted Answer

Adenosine

Answer

Adenosine induces maximal coronary hyperemia by causing maximal vasodilation, which is required for accurate FFR assessment of lesion physiologic significance.
