Objective:

To evaluate the acute performance of bioresorbable scaffolds (BRS) and drug-eluting stents (DES) using optical coherence tomography (OCT) and to assess the impact of specific plaque characteristics, such as calcific and fibrous plaques, on stent deployment and expansion.

Approach:

Key Findings:

• BRS showed similar stent expansion characteristics to DES despite previous concerns about thrombosis.
• Optimized implantation strategies using the PSP technique improved clinical outcomes for BRS.
• Plaque characteristics, particularly calcific and fibrous plaques, were assessed for their impact on stent performance.

Interpretation:

The study suggests that with proper implantation techniques, BRS can perform comparably to DES, potentially mitigating previous concerns regarding thrombosis.

Limitations:

• The study was limited to a single center and may not be generalizable, which could affect the applicability of the findings to broader populations.
• Sample sizes for previous studies referenced were small, necessitating further validation to confirm the results.

Conclusion:

The findings support the use of optimized implantation strategies for BRS in PCI, highlighting the importance of plaque characteristics in stent performance.
