Figure 1. Intravascular ultrasound and angiographic images (a, c) after stent placement and (b, d) at 1 year follow-up. The inner contour of the intravascular images presents the lumen area, the outer contour the stent or vessel area. At follow-up, plaque accumulation was evidenced in the stent (b), whereas the distal reference cross-section showed shrinkage without plaque accumulation (d).
