3D visualizations of FC thickness from representative IVOCT pullbacks with (A) large and (B) small lesions. Both lesions are by definition TCFAs because they have at least a point where the FC is under 65 µm. In the case of the large lesion, the FC had length = 28.2 mm, maximum angle = 271°, and surface area = 66.0 mm². These values suggest vulnerability as compared to the small lesion with attributes of an FC length of 4.9 mm, a maximum angle of 109°, and a surface area of 4.2 mm². For high-risk cases, clinicians may consider additional revascularization strategies such as a more aggressive statin treatment (see “Discussion”).
