Question 1

Which pharmacological agent is used to reverse heparin anticoagulation in the cath lab?

Accepted Answer

Protamine sulfate

Answer

Protamine sulfate binds and neutralizes heparin, rapidly reversing its anticoagulant effect.

Question 2

On a coronary angiogram, the left anterior descending (LAD) artery primarily supplies which cardiac territory?

Accepted Answer

Anterior wall and anterior two-thirds of the interventricular septum

Answer

The LAD supplies the anterior left ventricular wall, apex, and anterior septum via diagonal and septal perforator branches.

Question 3

The normal activated clotting time (ACT) target during percutaneous coronary intervention (PCI) with unfractionated heparin is:

Accepted Answer

200–250 seconds

Answer

An ACT of 200–250 seconds is the standard therapeutic target for PCI with heparin alone to prevent thrombosis while minimizing bleeding risk.

Question 4

Which of the following is a TRUE statement about ionic versus non-ionic contrast media?

Accepted Answer

Non-ionic contrast is associated with lower rates of allergic-type reactions

Answer

Non-ionic (low-osmolar) contrast agents carry a lower risk of anaphylactoid and hemodynamic reactions compared to high-osmolar ionic agents.

Question 5

A patient's aortic valve area calculated by the Gorlin formula is 0.6 cm². This finding is consistent with:

Accepted Answer

Severe aortic stenosis

Answer

An aortic valve area ≤0.6–1.0 cm² (with critical being <0.6 cm²) is classified as severe aortic stenosis per ACC/AHA guidelines.
