CCS Cardiovascular Treatment Procedures 2

Question 1

During transcatheter aortic valve replacement (TAVR), which vascular access site is most commonly used?

Accepted Answer

Femoral artery

Answer

The transfemoral approach is the most common access route for TAVR due to its lower complication rates and faster recovery.

Question 2

A patient undergoes coronary artery bypass grafting (CABG). The left internal mammary artery (LIMA) is preferentially used to bypass which vessel?

Accepted Answer

Left anterior descending artery

Answer

The LIMA-to-LAD graft has superior long-term patency rates compared to saphenous vein grafts, making it the preferred conduit for LAD bypass.

Question 3

Which pharmacologic agent is administered during a stress test when a patient cannot exercise adequately?

Accepted Answer

Dobutamine or adenosine

Answer

Pharmacologic stress agents such as dobutamine (inotropic) or adenosine/regadenoson (vasodilators) are used when patients cannot achieve adequate exercise.

Question 4

What is the purpose of using an intra-aortic balloon pump (IABP) in cardiogenic shock?

Accepted Answer

Provide counterpulsation to reduce afterload and improve coronary perfusion

Answer

The IABP inflates during diastole to augment coronary perfusion and deflates during systole to reduce afterload, supporting the failing heart.

Question 5

A patient with hypertrophic obstructive cardiomyopathy (HOCM) fails medical therapy. Which catheter-based procedure reduces the outflow obstruction?

Accepted Answer

Alcohol septal ablation

Answer

Alcohol septal ablation involves injecting alcohol into the first septal perforator artery to induce a controlled infarction and reduce the hypertrophied septum.
