  1. Which of the following describes a 'type A' coronary lesion morphology per the ACC/AHA classification?

    Answer: Discrete lesion <10 mm, concentric, non-angulated, smooth contour

    Type A lesions are discrete, concentric, accessible, and non-calcified, carrying the highest procedural success and lowest complication rates.

  2. Fractional flow reserve (FFR) of 0.75 in a 70% stenosis coronary lesion indicates:

    Answer: Hemodynamically significant ischemia — revascularization is warranted

    An FFR ≤0.80 (especially ≤0.75) indicates physiologically significant ischemia, supporting revascularization to improve outcomes.

  3. When using a thermodilution catheter to measure cardiac output, which injectate temperature produces the MOST accurate results?

    Answer: Iced saline (approximately 0–4°C)

    Iced injectate creates a larger temperature differential, improving signal-to-noise ratio and accuracy of the thermodilution curve.

  4. Which ECG finding is MOST concerning for left main coronary artery disease during stress testing or symptom onset?

    Answer: ST elevation in V1 and aVR with diffuse ST depression in other leads

    ST elevation in aVR with diffuse ST depression suggests global subendocardial ischemia, classically associated with left main or proximal LAD disease.

  5. The 'normal' pulmonary vascular resistance (PVR) in a patient without cardiopulmonary disease is approximately:

    Answer: 50–150 dynes·sec·cm⁻⁵

    Normal PVR is 50–150 dynes·sec·cm⁻⁵, far lower than systemic resistance, reflecting the low-resistance pulmonary circuit.

  6. During coronary intervention, 'no-reflow' phenomenon is BEST managed with which of the following agents?

    Answer: Intracoronary adenosine or verapamil

    Intracoronary vasodilators such as adenosine, verapamil, or nitroprusside are first-line treatments for no-reflow due to microvascular spasm and dysfunction.

  7. Which parameter is calculated using the formula: (MAP – CVP) / CO × 80?

    Answer: Systemic vascular resistance

    SVR = (MAP – CVP) / CO × 80, expressing the opposition the left ventricle overcomes to eject blood into the systemic circulation.
