Embolization of Fractured Bioresorbable Scaffold Struts Insights From 2- and 3-Dimensional Optical Coherence Tomography
A 58-year-old diabetic man underwent implantation of 3 overlapping Absorb bioresorbable vascular scaffolds (BVS) (2.5/28, 2.5/28, and 3.0/28 mm) (Abbott Vascular, Santa Clara, California) in a heavily calcified left anterior descending artery stenosis. Optical coherence tomography (OCT) revealed multiple fractures of the 3.0/28 BVS, leading to in-scaffold implantation of a zotarolimus-eluting stent (ZES) ( Figures 1A and 1B ). The 4-month angiography showed a severe edge in ZES restenosis treated with another stent. The OCT revealed an unexpected disappearance of BVS struts ( Figure 1C ) in the ZES segment and a nonocclusive cluster of polymeric ...
