  1. A 58-year-old with severe aortic stenosis (AVA 0.7 cm², mean gradient 52 mmHg) is asymptomatic. Which finding would prompt intervention?

    Answer: LV ejection fraction <50% on serial echocardiography

    Asymptomatic severe AS with LVEF <50% is a Class I indication for valve replacement due to evidence of LV dysfunction.

  2. Which finding on coronary angiography is most consistent with a fractional flow reserve (FFR) value of <0.80, indicating hemodynamically significant stenosis?

    Answer: 80% diameter stenosis in a large obtuse marginal branch supplying viable myocardium

    An 80% stenosis in a territory supplying viable myocardium is most likely to produce a pressure drop resulting in FFR <0.80.

  3. A patient with long QT syndrome type 1 (LQT1) presents after a near-syncopal episode during swimming. What is the most appropriate management?

    Answer: Initiate beta-blocker therapy and restrict swimming

    Beta-blockers are highly effective in LQT1 and mandatory after a symptomatic event; swimming is a specific trigger and should be restricted.

  4. Which statement about cardiac MRI in patients with known or suspected myocarditis is MOST accurate?

    Answer: T2-weighted imaging can detect myocardial edema, reflecting active inflammation

    T2-weighted CMR detects myocardial edema and is a key component of the Lake Louise criteria for myocarditis diagnosis.

  5. A patient develops ventricular fibrillation during a diagnostic coronary angiogram. After successful defibrillation, coronary arteries are found to be normal. What is the most likely diagnosis?

    Answer: Coronary vasospasm causing Prinzmetal angina

    Coronary vasospasm (Prinzmetal variant angina) can cause VF during angiography due to transient occlusive spasm even in angiographically normal arteries.

  6. In a patient with symptomatic heart failure with preserved ejection fraction (HFpEF, EF 58%), which intervention has the strongest evidence for reducing hospitalizations?

    Answer: SGLT2 inhibitor (empagliflozin or dapagliflozin)

    EMPEROR-Preserved and DELIVER trials demonstrated significant reduction in HF hospitalizations with SGLT2 inhibitors in HFpEF.

  7. Which congenital heart defect is most commonly associated with Down syndrome (trisomy 21)?

    Answer: Atrioventricular septal defect (AVSD)

    Atrioventricular septal defects (complete AV canal) are the most common congenital cardiac anomaly in patients with Down syndrome, occurring in ~40%.
