Insights
Bioresorbable vascular scaffolds treated chronic total occlusion but led to in-scaffold restenosis and aneurysm. A self-expandable stent was implanted to manage this complex complication.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Biomaterials Science
Background:
- Chronic total coronary artery occlusion poses treatment challenges.
- Bioresorbable vascular scaffolds (BVS) offer a promising alternative to metallic stents.
- Late complications after BVS implantation, such as restenosis and aneurysm, require careful management.
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.
