  1. Which drug is the preferred agent for acute rate control of atrial fibrillation with rapid ventricular response in a patient with decompensated heart failure and reduced EF?

    Answer: IV amiodarone

    IV amiodarone is preferred for rate control in AF with decompensated HFrEF because it avoids the negative inotropic effects of beta-blockers and non-dihydropyridine calcium channel blockers.

  2. A 55-year-old with dilated cardiomyopathy (EF 28%) and LBBB with QRS duration 165 ms is on optimized medical therapy. Which device therapy is indicated?

    Answer: Cardiac resynchronization therapy with defibrillator (CRT-D)

    CRT-D is indicated for HFrEF with EF ≤35%, LBBB morphology, and QRS ≥150 ms on GDMT with NYHA class II-III symptoms, improving survival and symptoms.

  3. Which feature on coronary CT angiography most accurately predicts a hemodynamically significant stenosis beyond anatomic narrowing?

    Answer: CT-derived fractional flow reserve (CT-FFR) ≤0.80

    CT-FFR ≤0.80 derived from coronary CTA identifies functionally significant lesions causing ischemia with accuracy comparable to invasive FFR.

  4. What is the most common inherited arrhythmia syndrome causing sudden cardiac death due to ventricular fibrillation with a structurally normal heart?

    Answer: Brugada syndrome

    Brugada syndrome, caused most commonly by SCN5A mutations, presents with coved-type ST elevation in V1-V3 and causes VF-related sudden death in structurally normal hearts.

  5. A patient undergoes primary PCI for STEMI. Post-procedure TIMI flow is 3 but has persistent chest pain and ST elevation. What is the most likely explanation?

    Answer: No-reflow phenomenon

    No-reflow occurs when epicardial flow is restored but microvascular obstruction prevents myocardial perfusion, causing persistent symptoms despite TIMI 3 flow.

  6. In a patient with acute decompensated heart failure, which finding on BNP or NT-proBNP level most reliably guides diuretic therapy titration during hospitalization?

    Answer: Serial BNP reduction of ≥30% from admission to discharge

    A ≥30% reduction in BNP from admission to discharge correlates with successful decongestion and predicts lower 30-day readmission and mortality risk.

  7. Which complication is most specifically associated with inferior STEMI extending to the right ventricle?

    Answer: Hypotension responsive to IV fluids with clear lungs

    RV infarction causes hypotension due to RV failure with low LV preload; the lungs remain clear because LV filling is reduced, and IV fluid loading improves cardiac output.
