  1. During pulmonary vein isolation (PVI) for atrial fibrillation ablation, esophageal temperature monitoring is used to prevent which serious complication?

    Answer: Atrio-esophageal fistula

    Atrio-esophageal fistula is a rare but often fatal complication of AF ablation caused by thermal injury to the posterior left atrial wall adjacent to the esophagus.

  2. A patient presents with signs of cardiac tamponade following a recent myocardial infarction. Pulsus paradoxus is measured at 18 mmHg. What is the hemodynamic mechanism responsible for pulsus paradoxus in tamponade?

    Answer: Ventricular interdependence compressing the LV during inspiration

    In tamponade, inspiratory RV filling expands the RV within the fixed pericardial space, compressing the LV (ventricular interdependence) and reducing LV stroke volume and systolic BP.

  3. Optical coherence tomography (OCT) is used during PCI. Compared to IVUS, what is the primary advantage of OCT?

    Answer: Superior near-field resolution for detailed strut-level imaging

    OCT provides 10-fold higher axial resolution (~15 µm) than IVUS, enabling detailed visualization of stent struts, tissue coverage, and plaque morphology.

  4. A patient with severe mitral regurgitation due to posterior leaflet prolapse is deemed suitable for MitraClip (transcatheter edge-to-edge repair). Which echocardiographic view is essential for guiding the transseptal puncture and clip deployment?

    Answer: Midesophageal bicaval view on TEE

    The midesophageal bicaval view on TEE clearly visualizes the atrial septum and guides optimal transseptal puncture height for MitraClip delivery.

  5. A post-cardiac surgery patient develops a new pericardial effusion with hemodynamic compromise 4 weeks after surgery. What is the most likely diagnosis and recommended treatment?

    Answer: Dressler syndrome (post-pericardiotomy syndrome); NSAIDs and colchicine

    Post-pericardiotomy (Dressler) syndrome is an immune-mediated pericarditis with effusion occurring weeks after cardiac surgery, treated with NSAIDs and colchicine.

  6. During tilt-table testing for unexplained syncope, the patient develops hypotension and bradycardia without a prodrome after 20 minutes of upright tilt. Which type of vasovagal response is this?

    Answer: Type 2B (cardioinhibitory with asystole)

    Type 2B vasovagal syncope is characterized by severe bradycardia/asystole (≥3 seconds) preceding or concurrent with blood pressure drop, classified by the VASIS criteria.

  7. A 65-year-old male with diabetes and chronic kidney disease (eGFR 32 mL/min) requires coronary angiography. Which strategy best minimizes contrast nephropathy risk while maintaining diagnostic accuracy?

    Answer: Use iso-osmolar contrast with pre-procedure hydration and limit contrast volume to <3× eGFR

    Using iso-osmolar contrast with pre-hydration and limiting contrast volume to <3× the eGFR in mL/min is the most evidence-supported strategy for CIN prevention in CKD patients.
