Bioresorbable vascular scaffolds technology: current use and future developments.

Area of Science:

• Interventional Cardiology
• Biomaterials Science
• Cardiovascular Research

Background:

• Coronary bioresorbable vascular scaffolds (BVS) represent an innovative therapeutic approach in interventional cardiology.
• The Absorb BVS™, composed of poly-L-lactide and poly-D,L-lactide releasing everolimus, is extensively studied and degrades within 2-3 years.

Purpose of the Study:

• To systematically review clinical outcomes of Absorb BVS™ studies.
• To evaluate technical improvements in the Absorb GT1 BVS™.
• To assess the advantages of BVS over traditional metallic stents.

Main Methods:

• Systematic analysis of observational and randomized trials on Absorb BVS™.
• Review of studies focusing on Absorb BVS™ clinical outcomes.
• Evaluation of technical advancements in Absorb GT1 BVS™.

Main Results:

• Absorb BVS™ provides temporary mechanical support, avoiding permanent vessel caging.
• Potential for preserved long-term endothelial function, structure, and future surgical revascularization.
• Recovery of natural vasomotion is a theoretical advantage.

Conclusions:

• Bioresorbable vascular scaffolds offer theoretical advantages over metallic stents, including temporary support and preservation of vessel function.
• Ongoing research and technical improvements are crucial for optimizing BVS therapy.
• Systematic analysis of clinical data is essential for understanding the long-term impact of BVS.
