5 FIGURE 4 Coronaryangiography and IVUS showed critical stenosis in the proximal right coronary artery, with abundant atheromatous plaque within the lesion before stenting (A). After successful abciximab-coated stent placement, the coronary artery had good patency, without residual stenosis (B). At 6-month follow-up coronary angiography and IVUS, no ISR in the previously stented right coronary artery was observed (C).
