Figure 3: (a) LV outflow tract showing bicuspid AV and a niche (arrow) in the interventricular septum. The LCA is critically stenosed (LV: Left ventricular, AV: Aortic valve LCA: Left circumflex artery, AA: Ascending arota, LAA: Left atrial appendage, MV: Mitral valve); (b) Fibrous tract (arrow) at the niche produced by the closed muscular ventricular septal defect (LVC: Left ventricular cavities, RVC: Right ventricular cavities); left anterior descending artery, (c and d) (scanned slide) critical stenosis by atheroma; (e) At shoulder S, there is fibrous cap FC erosion (arrows) with fresh thrombus. The core C is lipid rich (H and E, ×250)
