1. During right heart catheterization, a ‘dip and plateau’ (square root sign) in the ventricular pressure tracing is most characteristic of:
2. In echocardiography, the ‘apical sparing’ pattern of longitudinal strain (a bullseye plot with preserved apical function but severely reduced basal/mid function) is a hallmark of:
3. Which antiarrhythmic drug exhibits ‘reverse use dependence’ (meaning its action potential prolonging effect is greatest at slower heart rates)?
4. In typical Atrioventricular Nodal Reentrant Tachycardia (AVNRT), the reentrant circuit utilizes:
5. What is the specific mechanism of action for PCSK9 inhibitors (e.g., Evolocumab)?
6. In patients with acute anterior myocardial infarction, the appearance of biphasic T waves in leads V2-V3 during a pain-free interval is highly specific for:
7. The Austin Flint murmur, associated with severe aortic regurgitation, is functionally created by:
8. In patients with Tetralogy of Fallot, the primary determinant of the severity of cyanosis and clinical presentation is:
9. In cardiovascular hemodynamics, the Fick Principle calculates Cardiac Output (CO) using which parameters?
10. What is the most common conduction complication following Transcatheter Aortic Valve Replacement (TAVR) that requires intervention?
11. In patients with Mitral Valve Prolapse (MVP), performing a rapid squatting maneuver has what effect on the characteristic click and murmur?
12. A patient presenting with acute, severe tearing chest pain radiating to the back is found to have a Stanford Type B aortic dissection. Assuming no end-organ ischemia, what is the initial medical therapy of choice?
13. In patients with isolated native mitral valve stenosis, severity is typically quantified on echocardiography using:
14. Which primary immunosuppressive agent class forms the backbone of therapy in preventing rejection for post-cardiac transplant patients?
15. What is the specific electrophysiologic effect of hypercalcemia on a standard 12-lead ECG?
16. In Brugada Syndrome, which ion channel gene is most frequently mutated?
17. Which of the following Late Gadolinium Enhancement (LGE) patterns on Cardiac MRI is most characteristic of acute viral myocarditis?
18. A patient with Pulmonary Arterial Hypertension (PAH) is prescribed Bosentan. What is its mechanism of action?
19. In patients with a single ventricle physiology who have undergone a completed Fontan operation, what is a feared, chronic, life-threatening complication characterized by chronic severe diarrhea and edema?
20. In patients with isolated posterior myocardial infarction, what is the classic presentation on standard 12-lead ECG in leads V1 to V3?
21. Which physical exam finding is the hallmark of severe, fixed aortic stenosis?
22. In patients with a permanent ventricular pacemaker (VVI mode), ‘Pacemaker Syndrome’ is primarily caused by:
23. What severe congenital heart defect is heavily associated with maternal Lithium use during the first trimester?
24. In patients undergoing an acute anterior STEMI, rupture of the ventricular septum typically occurs:
25. Tachycardia utilizing a Mahaim fiber typically presents with an ECG showing:
