Relationship between angiographic late loss and target lesion revascularization after coronary stent implantation

Coronary stents result in large lumens with “room” to accommodate up to ∼0.5 to 0.65 mm of tissue (angiographic analysis segment late loss) before the likelihood of clinical restenosis (TLR) exceeds 5% to 10%. These data have important implications toward understanding the absolute and relative efficacy of drug-eluting stents.
