Flare spots (Figures 1A and 1B) are observed in intravascular optical coherence tomography (IVOCT) images of bioabsorbable stent struts in patients and have no analog in metallic stents. Gutiérrez-Chico et al.(1) proposed that flare spots were located at hinge points where the highest strain is experienced during deployment, suggesting that they represent micro-crazes (fine lines) in the polymer. Nonetheless, the mechanism for the presence of flare spots in IVOCT images, and the large variation in their appearance where no two are alike, is not known. In this study, micro-CT and IVOCT images of a bioabsorbable stent deployed in a cylindrical phantom blood vessel were coregistered and compared in order to investigate the underlying mechanism for presence of flare spots in IVOCT images.
