Figure 1. Patient with ST-elevation myocardial infarction and multivessel disease. Patient with STEMI (*) and an occluded circumflex artery who remained hemodynamically stable during PCI. Both PCI of the infarct-related artery and the non-culprit lesion were performed under OCT guidance. In the circumflex artery, OCT revealed thrombus (A), whereas in the left anterior descending artery, it showed a mixed fibrous and lipid plaque (B). Post-stenting OCT demonstrated stent malapposition (C), stent-edge dissection (D), and plaque protrusion after stent implantation (E). ESC: European Society of Cardiology; FFR: fractional flow reserve; IVI: intravascular imaging; OCT: optical coherence tomography; PCI: percutaneous coronary intervention; STEMI: ST-elevation myocardial infarction.
