Figure 3 Plaque classification by intravascular ultrasound–virtual histology distinguishes between intimal thickening (A, B), and more vulnerable lesions, such as fibroatheroma (C, D, E). In thin cap fibroatheroma (TCFA) (D), the necrotic core is lying on the surface of the plaque. Compared with the fibroatheroma (C) the fibrous cap is not visible. TCFA with multiple layers of necrotic areas (E) suggests multiple previous ruptures. (A) Adaptive intimal thickening; (B) pathological intimal thickening; (C) fibroatheroma; (D) IVUS‐defined TCFA; (E) TCFA, multiple layer; (F) fibrocalcific plaque.
