Thin-cap fibroatheroma in non-ischemic lesions. Optical coherence tomography images of thin-cap fibroatheromas (A, C) with the respective corresponding angiography (B, D) in patients with diabetes mellitus are shown. Thin-cap fibroatheromas are characterised by lipid-rich, non-calcified plaque with necrotic cores, in which the thinnest part of the fibrous cap measures ≤ 65 μm. A thin-cap fibroatheroma is the main precursor substrate for plaque rupture. In the optical coherence tomography images, lipid-rich plaques exhibit regions with poor signal and poorly defined borders, which are circularly present in both lesions. Part of the thinnest fibrous cap (shown with *) is magnified and measures ≤ 65 μm. The lesions were both of non-ischemic nature as determined by fractional flow reserve measurements. The cylinders in the angiographic images indicate the location of the lesions
