Bioresorbable Vascular Scaffold Korean Expert Panel Report.

Area of Science:

• Cardiovascular Medicine
• Biomaterials Engineering
• Interventional Cardiology

Background:

• Bioresorbable vascular scaffolds (BRS) are designed to provide temporary support and drug delivery, degrading into harmless byproducts.
• Unlike metallic drug-eluting stents (DESs), BRS aim to avoid long-term complications.
• Recent clinical data have highlighted safety and efficacy concerns regarding first-generation BRS.

Purpose of the Study:

• To review the existing clinical evidence on the safety and efficacy of Bioresorbable Vascular Scaffold (BRS) implantation.
• To provide guidance on optimal practices for BRS use, addressing patient and lesion selection, implantation techniques, and post-procedure management.
• To establish appropriate criteria for BRS application in the absence of long-term Korean clinical data.

Main Methods:

• Systematic review of randomized trials and registry studies on BRS.
• Analysis of clinical outcomes, including safety and efficacy endpoints.
• Synthesis of evidence to formulate recommendations for clinical practice.

Main Results:

• First-generation BRS have demonstrated both potential benefits and significant clinical concerns regarding safety and efficacy.
• Limited long-term data currently exist, particularly within the Korean population.
• Variability in outcomes suggests a need for careful patient and lesion selection.

Conclusions:

• Optimal patient and lesion selection are critical for successful BRS implantation.
• Standardized implantation techniques and appropriate post-procedural management are essential to mitigate risks.
• Further research and long-term data are necessary to fully elucidate the role of BRS in cardiovascular interventions.
