Figure 1. (a) Curved multiplanar reformat of the left main and left anterior descending artery (LAD) depict a small non-significant calcified plaque in the proximal LAD (white arrow), and an elongated segment of myocardial bridging affecting the proximal and mid segments of the LAD (black arrow). (b) Curved multiplanar reformat of the left main proximal LAD and first diagonal arteries shows a small non-significant calcified plaque in the proximal LAD (white arrow), an elongated segment of myocardial bridging affecting the proximal and mid segments of the LAD (black arrow) and myocardial bridging of the origin and very proximal portion of the first diagonal artery (arrowhead). (c) Cross sectional reformat of the proximal LAD calcified plaque perpendicular to the long axis of the artery clearly demonstrates a relatively wide patent lumen (+) adjacent to an eccentric small calcified plaque (*), indicating its non-significance.
