Spread-out plots of a scaffolded coronary segment at baseline at 6- and 24-month follow-up. The x axis represents the distance from the distal end of the
scaffold, and the y axis represents the circumferential segment (angle) where the different plaque components are located. Fibrotic tissue is indicated with
green and calcific with white. The orange markers, at the spread-out plots at baseline (Aii) and follow-up (Bii, Cii), correspond to the axial position of the
metallic markers and are shown in panels Ai, Bi, Ci (proximal markers) and in panels Av, Bv, and Cv (distal markers). The blue dashed lines indicate the
location of the frames shown in panels Aiii, Biii, and Ciii. The yellow spot in these panels denotes the zero-degree location in the spread-out scaffold plots
and the yellow arrow the counterclockwise direction followed to evaluate the circumferential location of the detected tissues. The white arrows correspond
