Figure 2. Optical frequency domain imaging and coronary angioscopy findings before excimer laser coronary angioplasty (A-D), and after excimer laser coronary angioplasty (E-H). (A) A cavity (red arrows) and fibroatheroma (yellow asterisks). (B) Circumferential fibrous plaque with a minimum lumen area of 2.8 mm2. (C) On angioscopy, a cavity due to plaque rupture is confirmed at the 1–2 o'clock (red arrows) position, and yellow plaque is confirmed at the 9 o'clock position (yellow asterisks). (D) Yellow arrowhead indicates stent strut. (E) On optical frequency domain imaging, ablation of the surficial plaque is confirmed (white arrows). (F) Ablation of surficial fibrous plaque is confirmed (yellow arrowhead). The minimum lumen area is 2.9 mm2. (G) On angioscopy, surficial minor bleeding is confirmed at the 9 o'clock position (yellow arrows). (H) Yellow arrowheads indicate the stent strut with neointima peeled off. Figure 2.
