Figure 1. Lumen area changes by OCT after BMS (top) vs. BRS (bottom) deployment in swine model during 4-year period. A significant increase in lumen area of BRS vs. BMS occurred between 2 and 4 years, as a result of positive vessel remodeling and plaque regression. OCT: Optical coherence tomography; BMS: Bare-metal stents; BRS: Bioresorbable scaffolds.
