Chapter 39. Special Considerations: Small Vessel and Diffuse Disease
Independent predictors of underestimating the true coronary vessel size based on a disparity between intravascular ultrasound (IVUS)–determined reference lumen diameter and coronary angiography include all of the following except:
B. Proximal left anterior descending artery (LAD) lesion location
C. Coronary calcification
True or false? Small vessel size has been associated with higher restenosis rates. However, equally expanded stents (equal minimum stent area) in different-sized arteries have equivalent restenosis risk.
True or false? For calcified small coronary lesions, prestent atherectomy has been associated with lower restenosis rate.
True or false? Compared to bare metal stents, percutaneous transluminal coronary angioplasty has a higher rate of target lesion revascularization.
True or false? Compared to drug-eluting stents, bare metal stents in small vessels have a lower incidence of negative remodeling over the first year.
The use of bioresorbable scaffolds in small vessels has been associated with higher stent thrombosis compared to metallic second-generation drug-eluting stents in vessels smaller than which size?
