From the epicardial adipose tissue to vulnerable coronary plaques

Figure 1 A 64-year-old male was admitted at our hospital because of progressive angina. A: Coronary angiogram demonstrated a complex stenosis in the mid segment of the circumflex coronary artery; B-F: Optical coherence tomography revealed a large complex thin-cap fibroatheroma (arrows) proximal and at the site of the stenosis. The fibrous cap covering the lipid rich plaque had a variable thickness and in its thinnest part measured 55 μm (arrows in D). Distally, the same plaque had large lipidic core and an image compatible with a rupture site (*) (E). Please note that residual lining red thrombus with a clear dorsal shadowing was also detected at some sites (+). Finally, at the most severe site (F), a fibrous plaque was noted.
