A 20% stenosis of the RCA ostium, a very tight calcified lesion in the proximal RCA segment (stent material visible) and significant lesions at the crux (Figures 1A and 1B) were discovered. The distal RCA showed only mild lesions (Figure 1A). Ab OCT images]), but no shadows of stent struts were present at this location. At 9 o'clock multiple concentric layers of stent struts were spotted with shadows obscuring the vessel wall, indicating that there were crushed stent segments (Figure 1A, [Aa and Ab OCT images]). The MLA was 2.26 mm2 (Figure 1A [Ac OCT image]).
