A 7 Fr femoral sheath (Terumo¢ç) was inserted through the right femoral artery and left coronary artery was engaged with a 7 Fr JL 4 guiding catheter. 0.014-inch BMW 190 cm wire and 0.014-inch Sion blue wire were inserted into LAD and diagonal branch, respectively. Before the intervention, OCT was used to identify lesion characteristics and mechanism of ISR at LAD, in which diffuse neointimal hyperplasia through the stent strut of BVS was identified with OCT imaging evaluation ( Movie 4). Lesion modification with non-compliance 3.0 x 15 mm balloon was used. Two Xience Sierra stents sized 3.0 x 23 mm and 3.5 x 28 mm at LAD ISR lesion were inserted. NC Emerge balloon sized 3.0 x 15 mm was used for stent optimization. OCT was checked and showed no immediate complications with adequate stent area ( Movie 5). The final angiogram showed no stenotic lesion and good flow ( Movie 6).
