Dissolvable heart stent could replace permanent implants
NCT ID NCT06919562
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new type of heart stent that dissolves over time, unlike permanent metal stents. The trial will enroll 117 people with stable coronary artery disease to see if the new stent, placed with special imaging guidance, works safely and effectively. The goal is to reduce long-term problems like inflammation and make future heart surgeries easier.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MeRes100 thin-strut bioresorbable scaffold
- What this could lead to
- If successful, this could lead to a safer way to open blocked heart arteries that dissolves over time, potentially reducing long-term complications from permanent stents.
- What could go wrong
- This is a small, early feasibility study (117 people) testing a new device and technique. The scaffold may still cause blood clots or fail to perform as well as current standard stents.

Inclusion Criteria: 1. Stable coronary artery disease with one or more significant epicardial stenosis in native coronary arteries suitable for OCT or IVUS-guided PCI with BRS implantation. 2. Subject must be at least 18 years of age 3. Written consent to participate in the study Exclusion Criteria: 1. Culprit lesions in the setting of acute coronary syndrome. 2. Lesions with severe calcification. 3. Lesions in a coronary artery with severe tortuosity. 4. Left main coronary artery lesions. 5. Bifurcation lesions. 6. Ostial lesions. 7. Lesions with a difference in proximal and distal reference diameter of \>0.5 mm by visual judgement of the coronary angiogram by the treating operator. 8. Treatment of in-stent restenosis or stent thrombosis. 9. History of definite stent thrombosis. 10. Lesions in coronary artery bypass grafts. 11. Lesions not suitable for OCT or IVUS catheter delivery and imaging, e.g. due to tortuosity or distal localisation. 12. Creatinine Clearance ≤ 30 ml/min/1.73 m2 as calculated by MDRD formula for estimated GFR. 13. Contraindication to dual antiplatelet therapy with aspirin and a P2Y12 inhibitor or (if indicated) NOAC and P2Y12 inhibitor. 14. Planned non-deferrable major surgery after PCI. 15. Known comorbidity associated with a life expectancy \<1 year. 16. Unable to understand and follow study-related instructions or unable to comply with study protocol.
