Managing Bioabsorbable Vascular Scaffold Failure: Combined Scaffold Restenosis and Late-Acquired Coronary Aneurysm Treated With Self-Expandable Stent

Abstract A 50-year-old man underwent coronary angiography for stable angina with evidence of chronic total occlusion of the right coronary artery. Chronic total occlusion recanalization was performed with implantation of 4 overlapping bioresorbable vascular scaffolds. At 12 months, elective follow-up coronary angiography documented an asymptomatic 90% in-scaffold restenosis of the right coronary artery located in the mid portion of a newly late-acquired aneurysm. To address the challenging issue introduced by the varying reference vessel diameters, a self-expandable stent was implanted.
