  Figure 1 Coronary angiographies (A, D) showing focal bifurcation lesions. OCT identified atheromas with a characteristic layered appearance, confirming the presence of healed plaques (B, E). High-definition 35–65 MHz IVUS revealed crescent-shaped, hypoechoic layers clearly demarcating underlying hyperechoic plaques (C, F). These layered plaques exhibited low lipids on NIRS.IVUS = intravascular ultrasound; NIRS = near-infrared spectroscopy; OCT = optical coherence tomography.
