case_images: Coronary angiography (CAG) findings. CAG showed 90% stenosis in the mid-left anterior descending (LAD) coronary artery. The stenosis looked smoother than typical arteriosclerotic stenosis. No other lesions were detected.

case_images: CAG showed a 90% stenosis in the mid-left anterior descending (LAD) coronary artery (Figure 1).
case_images: Intravascular ultrasound (IVUS) findings: (a, c) IVUS finding of normal coronary artery in our patient's proximal and distal left anterior descending (LAD) arteries, (b) IVUS findings of our patient's LAD lesion demonstrating a thicken black layer beneath the intima (arrowheads) and external elastic membrane which is the outside edge of the medial (arrow).

case_images: IVUS (View It; Terumo, Tokyo, Japan) catheter was inserted to visualize the characteristics of the LAD lesions. IVUS demonstrated a thickened black layer beneath the intima at the lesion and nearly normal vessel wall at the proximal and distal LAD (Figure 2).
