Figure 7.

VIE appearance of calcified plaques. An eccentric calcified plaque is formed in the left anterior descending on a 2D axial image ((a) arrows), and corresponding VIE shows the smooth protruding appearance in the superior lumen of left anterior descending ((b) long arrows). The plaque is close to the ostium of left circumflex (LCx) and covers the other ostia of left coronary side branches (short arrows). A concentric plaque is present in the left anterior descending in another patient on 2D axial images ((c) arrows), and corresponding VIE shows intraluminal smooth appearance around the coronary lumen ((d) arrows).
