During transcatheter aortic valve replacement (TAVR), which vascular access site is most commonly used?
Answer: Femoral artery
The transfemoral approach is the most common access route for TAVR due to its lower complication rates and faster recovery.
A patient undergoes coronary artery bypass grafting (CABG). The left internal mammary artery (LIMA) is preferentially used to bypass which vessel?
Answer: Left anterior descending artery
The LIMA-to-LAD graft has superior long-term patency rates compared to saphenous vein grafts, making it the preferred conduit for LAD bypass.
Which pharmacologic agent is administered during a stress test when a patient cannot exercise adequately?
Answer: Dobutamine or adenosine
Pharmacologic stress agents such as dobutamine (inotropic) or adenosine/regadenoson (vasodilators) are used when patients cannot achieve adequate exercise.
What is the purpose of using an intra-aortic balloon pump (IABP) in cardiogenic shock?
Answer: Provide counterpulsation to reduce afterload and improve coronary perfusion
The IABP inflates during diastole to augment coronary perfusion and deflates during systole to reduce afterload, supporting the failing heart.
A patient with hypertrophic obstructive cardiomyopathy (HOCM) fails medical therapy. Which catheter-based procedure reduces the outflow obstruction?
Answer: Alcohol septal ablation
Alcohol septal ablation involves injecting alcohol into the first septal perforator artery to induce a controlled infarction and reduce the hypertrophied septum.
Which finding on coronary angiography would most strongly indicate the need for fractional flow reserve (FFR) measurement?
Answer: Intermediate stenosis of 40–70% in a major coronary artery
FFR is most useful for intermediate lesions (40–70%) where visual assessment alone cannot reliably determine hemodynamic significance.
After placement of a drug-eluting stent (DES), dual antiplatelet therapy (DAPT) is typically continued for at least how long?
Answer: 12 months
Current guidelines recommend at least 12 months of DAPT after DES implantation in ACS patients to prevent late stent thrombosis.
