View larger version (189K): [in a new window]   Figure 1 Different patterns of vascular remodeling in intravascular ultrasound. (A) Shows an example of adaptive remodeling with the external elastic membrane at the lesion site being larger than that in the proximal reference segment. (B) Exhibits the physiological tapering from the proximal to the distal direction ("intermediate remodeling"). (C) Depicts a constrictively remodeled lesion, with a significantly smaller external elastic membrane at the lesion site than in the distal reference segment.

View larger version (26K): [in a new window]   Figure 2 Kaplan-Meier survival curves with log-rank test for (A) composite MACE, (B) target lesion restenosis and (C) nontarget de novo stenosis. The curves reveal a significantly worse outcome for patients with AR during the observation period of one year. Solid diamond = group AR; solid circle = group CR; solid square = group IR. AR = adaptive remodeling; CR = constrictive remodeling; IR = intermediate remodeling; MACE = major adverse cardiac event.
