OCT guidance during PCI. (A) OCT after stent placement showing well-apposed stent. B, Malapposed stent struts visualized with OCT which led to postdilation with a larger balloon. C, Stent struts visualized at ostium of the first diagonal branch of the left anterior descending coronary artery. For bifurcation angioplasty, OCT guidance can be used to select the distal most cell for passing guidewire. D, Two layers of well-apposed stent struts visualized after bifurcation angioplasty with Crush technique. OCT, optical coherence tomography
