  1. The MitraClip procedure treats mitral regurgitation by:

    Answer: Clipping the mitral leaflets together to create a double-orifice valve

    The MitraClip grasps and approximates the anterior and posterior mitral leaflets at the regurgitant jet, reducing MR by creating a double-orifice configuration.

  2. During PCI of a chronic total occlusion (CTO), which crossing technique involves advancing a wire through the subintimal space and re-entering the true lumen distal to the occlusion?

    Answer: Subintimal tracking and re-entry (STAR technique)

    The STAR technique intentionally creates a subintimal channel and uses re-entry devices to regain the true lumen distal to a CTO.

  3. Left atrial appendage (LAA) occlusion with the Watchman device is used as an alternative to long-term anticoagulation in patients with atrial fibrillation who have:

    Answer: High stroke risk but contraindication to long-term anticoagulation

    The Watchman device seals off the LAA (source of ~90% of AF-related thrombi) in patients with elevated stroke risk who cannot safely take oral anticoagulants.

  4. Which measure is used to assess the physiologic significance of a coronary stenosis using a pressure wire, without administering hyperemic agents?

    Answer: Instantaneous wave-free ratio (iFR)

    iFR is measured during the diastolic wave-free period when microvascular resistance is naturally minimal, allowing lesion assessment without adenosine.

  5. A patient receiving thrombolytic therapy for STEMI develops sudden neurologic deficits 2 hours after drug administration. The most likely diagnosis is:

    Answer: Intracranial hemorrhage

    Intracranial hemorrhage is the most feared complication of thrombolytic therapy, occurring in approximately 0.5–1% of cases, and presents with acute neurologic deterioration.

  6. Optical coherence tomography (OCT) is preferred over intravascular ultrasound (IVUS) for assessing stent deployment because:

    Answer: OCT provides higher resolution imaging to detect malapposition and edge dissections

    OCT's near-infrared light provides 10–15 µm resolution (vs. 100–150 µm for IVUS), enabling detailed assessment of stent strut apposition, coverage, and edge dissections.

  7. Which complication of endomyocardial biopsy performed via the jugular or femoral vein is most common?

    Answer: Ventricular perforation and tamponade

    RV free wall perforation causing pericardial tamponade is the most serious and relatively most common complication of endomyocardial biopsy, occurring in 0.1–0.5% of cases.
