Relationship between high shear stress and OCT-verified thin-cap fibroatheroma in patients with coronary artery disease
Fig 2
High mean wall shear stress in the proximal segment of coronary lesions is associated with the presence thin-cap fibroatheroma verified by optical coherence tomography.
Color-coded WSS maps for two representative cases from patients with (A) thin-cap fibroatheroma lesion identified by OCT with minimal fibrous cap thickness 60 μm (A, inset) and WSS measured in the proximal segment of the lesion 16.5 Pa and (B) lesion with thick fibrous cap of 170 μm (B, inset) and proximal WSS 3.81 Pa. FCT = fibrous cap thickness; TCFA = thin-cap fibroatheroma; WSS = wall shear stress.
