Chapter 29. Basic Stent Deployment Techniques

When used for pretreatment before stenting, how does use of the AngioSculpt compare to balloon angioplasty?

A. With comparable-sized devices, resultant cross-sectional areas (CSAs) are similar.

B. With comparable-sized devices, cross-sectional area is greater with AngioSculpt regardless of lesion complexity.

C. With comparable-sized devices, results with AngioSculpt are better in calcified or long lesions, but not other lesions.

D. When used with comparable-sized devices, high-pressure balloon angioplasty generally results in larger CSA than AngioSculpt.

The correct answer is B

After inflation to 16 atm with typical balloons, what is the average ratio of in vivo versus ex vivo minimum lumen diameter?

A. 0.75

B. 0.85

C. 0.95

D. 1.00

The correct answer is A

To minimize the risk of DES restenosis using IVUS, what is the best approach to follow?

A. Attempt to achieve minimal in-stent cross sectional area of >5.5 mm2 for all stents.

B. Attempt to achieve minimal in-stent cross sectional area of >5.5 in vessels with reference diameters 2.25-3.00 mm.

C. Attempt to achieve in-stent cross sectional area of >80% of adjacent normal reference segments.

The correct answer is C

Which of the following imaging modalities most closely approximates in-vivo vessel dimensions?

A. QCA

B. IVUS

C. OCT

D. CTA

The correct answer is C

Which of the following is least closely related to the risk of stent thrombosis?

A. Outflow narrowing.

B. Poor stent expansion.

C. Residual dissection.

D. Slow flow.

The correct answer is A
