Summary
High-pressure post-dilation of bioresorbable vascular scaffolds (BVS) appears safe. Optimizing inflation duration and pressure stabilization is key for achieving ideal BVS expansion and preventing complications.
Area of Science:
- Cardiovascular medicine
- Biomaterials science
- Medical device engineering
Background:
- Current bioresorbable vascular scaffolds (BVS) possess thick struts and limited radial strength, necessitating precise deployment to avoid underexpansion and fracture.
- Optimal deployment strategies for BVS are crucial for ensuring device efficacy and patient safety.
Discussion:
- This study investigated the safety of high-pressure post-dilation (mean 28 atm) for BVS using noncompliant balloons.
- The findings indicate that high-pressure post-dilation can be safely performed, potentially improving scaffold expansion.
Key Insights:
- Very high-pressure post-dilation (mean 28 atm) of current BVS is suggested to be safe.
- Achieving optimal scaffold expansion requires careful attention to deployment technique.
Outlook:
- Future research should focus on the impact of inflation duration and pressure stabilization on BVS expansion.
- Optimizing deployment protocols may enhance the clinical performance and reduce complications associated with BVS.
