Long-term outcomes of bioresorbable vascular scaffolds (BVS) remain unclear. This case study shows a 10-year satisfactory outcome for BVS comparable to drug-eluting stents (DES), highlighting key implantation techniques.
Area of Science:
- Cardiovascular Medicine
- Biomaterials Science
Background:
- Bioresorbable vascular scaffolds (BVS) were developed for transient mechanical support and vascular function restoration.
- Concerns regarding higher scaffold thrombosis rates with BVS compared to metallic drug-eluting stents (DES) have been raised.
- Very long-term outcomes of BVS require further investigation.
Observation:
- A 71-year-old male with stable angina received both BVS and DES in the same coronary vessel in 2014.
- Follow-up angiography and intravascular optical coherence tomography were performed 10 years post-implantation.
- Both the BVS and DES demonstrated satisfactory outcomes at the 10-year mark.
Findings:
- The 10-year outcome of the BVS was comparable to the DES in the same patient and vessel.
- Successful long-term BVS performance was observed.
- No significant adverse events related to the BVS were reported up to 10 years.
Implications:
- This case highlights the importance of careful patient and lesion selection for BVS implantation.
- Proper sizing and implantation techniques, including predilatation and postdilatation, are critical for successful long-term BVS outcomes.
- BVS may offer a viable alternative to DES when appropriate selection and implantation techniques are employed, potentially leading to restored vascular function.
