  1. Ventricular tachycardia during left heart catheterization is MOST commonly triggered by:

    Answer: Catheter contact with the ventricular endocardium

    Mechanical irritation of the ventricular myocardium from catheter tip contact is the most frequent cause of catheter-induced VT during left heart cath.

  2. In the sheath-to-catheter size conversion, a 6 French sheath accommodates catheters up to which size?

    Answer: 6 French

    A 6 French sheath is sized to accommodate a 6 French catheter; the sheath inner lumen matches the outer diameter of the compatible catheter.

  3. The 'TIMI flow grade' system classifies coronary blood flow from 0 to 3. TIMI 2 is defined as:

    Answer: Partial perfusion — contrast passes but fills and clears the distal vessel slowly

    TIMI 2 indicates partial reperfusion: contrast does opacify the distal vessel but clearing is slower than in an unobstructed artery.

  4. A patient with mitral regurgitation will show a prominent 'V wave' on the pulmonary artery wedge pressure tracing. This V wave represents:

    Answer: Passive left atrial filling against a closed mitral valve during ventricular systole

    V waves occur during ventricular systole when regurgitant flow from the LV rapidly fills the LA, generating a high-pressure wave visible on the wedge tracing.

  5. Which of the following is the PRIMARY indication for intra-aortic balloon pump (IABP) counterpulsation?

    Answer: Cardiogenic shock or hemodynamic instability refractory to medical therapy

    IABP is indicated for cardiogenic shock, acute MI with hemodynamic compromise, or high-risk PCI support to augment diastolic coronary perfusion and reduce afterload.

  6. During percutaneous coronary intervention, a coronary dissection that involves the coronary media and results in reduced TIMI flow is classified as NHLBI type:

    Answer: Type E or F

    NHLBI types E and F dissections involve spiral luminal filling defects or total occlusions with no distal flow, representing the most severe dissection categories.

  7. Which safety measure is MOST effective in reducing operator radiation dose during fluoroscopy in the cath lab?

    Answer: Maximizing distance from the X-ray tube and using suspended lead shields

    Maximizing distance (inverse square law) combined with ceiling-suspended and table-mounted lead shields provides the greatest dose reduction for cath lab personnel.
