    Effect of plaque composition, morphology, and burden on DESolve novolimus-eluting bioresorbable vascular scaffold expansion and eccentricity — An optical coherence tomography analysis

    Objective This study of patients treated with novolimus-eluting bioresorbable scaffold (BRS) investigated the impact of plaque burden on the acute mechanical performance of the BRS and the short-term outcome. Methods A total of 15 patients were enrolled. The following parameters were derived from optical coherence tomography (OCT) during the final pullback: mean and minimum area, residual area stenosis, incomplete strut apposition, tissue prolapse, scaffold expansion index (SEI), scaffold eccentricity index (SEC), symmetry index, strut fracture, and edge dissection. Fibrous plaque (FP) and calcific plaque (CP) characteristics were measured at each 200 μm longitudinal cross-section. The patients were divided into two ...
