Abstract

We report a case of minimal acute recoil detected by optical frequency-domain imaging (OFDI) following bioresorbable scaffold (BRS) implantation for the treatment of a fibrocalcific lesion. The second OFDI pullback (8 minutes later) was performed to evaluate the distal dissection. We measured scaffold area every 0.25 mm and acquired a total of 115 paired cross-sections. Paired t-test demonstrated that minimal acute recoil was observed in this fibrous lesion and uncompressed dissection site with calcified plaque. This case demonstrates that acute recoil appears to be dependent upon plaque characteristics and the presence of malapposed struts after BRS implantation.
