OCT in bifurcation angioplasty. (A) Showed the final angiogram picture after LM bifurcation angioplasty with two stents using the DK crush technique. The angiographic result for LCx ostium was satisfactory but OCT pullback of the main branch (MB) after final kissing balloon inflation (KBI) showed hanging stent struts (red) across LCx ostium on the cross-sectional view (B), on 3D reconstruction (C), and on the rendered stent view (D). The same patient presented with crescendo angina after 9 months, and angiography showed LCx ostial ISR (E). OCT pullback of MB showed complete endothelization of hanging stent struts across LCx as a cause of ostial ISR (F,G).
