OCT detected BRS and DES complications. a OCT image of intimal dissection at the edge of Absorb scaffold (arrow), b PA caudal view of the same scaffold implanted in proximal LAD (oval shape) in which edge dissection could not be identified, c OCT image of calcium spike inducing scaffold fracture with loss of the expected scaffold circularity, d PA cranial view of the same scaffold implanted in mid LAD (oval shape) without evidence of fracture, e OCT image of scaffold fracture in the form of overriding contiguous struts post culotte bifurcation stenting, f post successful stenting of the same scaffold using DES, g OCT showing malapposed scaffold struts, h magnified picture showing scaffold struts clearly separated from the vessel wall, i OCT picture showing metallic struts malapposition with posterior dropout, and j magnified picture showing that the axial distance between the strut’s surface and the luminal surface exceeds the strut thickness in the malapposing struts
