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?

++
++
++

++
++

B. 0.85

++
++

C. 0.95

++
++

D. 1.00

+

++
++

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 is least closely related to the risk of stent thrombosis?

++
++
++

A. Outflow narrowing.

++

C. Residual dissection.

++
++

D. Slow flow.
