  1. During cardiac catheterization, a patient's oxygen saturation step-up is detected at the right ventricular level. What is the most likely diagnosis?

    Answer: Ventricular septal defect

    An oxygen saturation step-up at the RV level indicates a left-to-right shunt at the ventricular level, consistent with a ventricular septal defect.

  2. Which parameter measured during right heart catheterization is most useful for diagnosing pulmonary arterial hypertension (PAH) versus pulmonary venous hypertension?

    Answer: Pulmonary capillary wedge pressure (PCWP)

    A PCWP ≤15 mmHg distinguishes pre-capillary PAH from post-capillary (pulmonary venous) hypertension caused by left heart disease.

  3. A cardiovascular specialist performs a pericardiocentesis for cardiac tamponade. After needle entry, which finding confirms intrapericardial position before catheter advancement?

    Answer: Injection of agitated saline showing microbubbles in pericardial space on echo

    Injecting agitated saline and visualizing microbubbles in the pericardial space on echocardiography confirms correct needle placement before catheter advancement.

  4. What is the recommended activated clotting time (ACT) target during percutaneous coronary intervention (PCI) when unfractionated heparin is used without a glycoprotein IIb/IIIa inhibitor?

    Answer: 250–350 seconds

    The ACT target for PCI with unfractionated heparin alone is 250–350 seconds to balance anticoagulation efficacy and bleeding risk.

  5. A patient undergoing cardioversion for persistent atrial fibrillation has an INR of 1.8 despite warfarin therapy. What is the most appropriate next step according to current guidelines?

    Answer: Perform TEE to rule out left atrial thrombus before cardioversion

    TEE-guided cardioversion is an acceptable alternative to 3–4 weeks of therapeutic anticoagulation when the INR is subtherapeutic, as it can rule out left atrial appendage thrombus.

  6. During device implantation, a cardiac implantable electronic device (CIED) pocket infection is identified 3 weeks post-implant. What is the definitive management?

    Answer: Complete device and lead extraction with antibiotics

    Complete system extraction combined with appropriate antibiotic therapy is the definitive treatment for CIED pocket infection to prevent persistent infection and endocarditis.

  7. In the hemodynamic assessment of constrictive pericarditis, what echocardiographic Doppler finding most distinguishes it from restrictive cardiomyopathy?

    Answer: Respiratory variation >25% in mitral inflow E velocity

    Exaggerated respiratory variation (>25%) in mitral inflow E velocity reflects ventricular interdependence, a hallmark of constrictive pericarditis not seen in restriction.
