Figure

• 

  Figure 1 Coronary angiography images. The black arrows indicate a mild stenotic lesion in the middle portion of left anterior descending coronary artery in the left anterior oblique cranial projection (A) and right anterior oblique cranial projection (B).

• 

  Figure 2 OCT images with and without a guidewire. (A and A′) Intravascular OCT (black arrow) was performed in the LAD with a guidewire (white arrowheads, Supplementary Video 1) and without a guidewire (Supplementary Video 2). (B) The longitudinal view of the OCT with a guidewire exhibited guidewire artifact (yellow asterisks). (B′) The longitudinal view of the OCT without a guidewire revealed the plaque erosion (white arrowheads). (C-F) OCT revealed the suspicious presence of an intracoronary thrombus adjacent to the acoustic shadow from the guidewire artifact (yellow asterisk) from 4 to 7 o'clock. (C′-F′) After removal of the guidewire, the corresponding OCT images revealed the plaque erosion (white arrowhead) with an attached thrombus overlying an intact fibrous cap. OCT = optical coherence tomography.
