What is the maximum percentage of plaque burden that is acceptable at the stent edge in BSC's post stent workflow?

• A. 30%
• B. 50%
• C. 70%
• D. 90%

Answer: (B)

The maximum percentage of plaque burden that is acceptable at the stent edge in BSC's post-stent workflow is established at 50%. This threshold is significant because it helps ensure that the stented area has adequate blood flow and reduces the risk of restenosis, which is the re-narrowing of the artery following stent placement. A plaque burden exceeding this percentage could compromise the effectiveness of the stent, potentially leading to complications such as clot formation or inadequate perfusion of the tissue supplied by the artery.

In clinical practice, maintaining this standard is crucial for optimizing patient outcomes, as higher plaque burden percentages can correlate with increased rates of adverse events post-stenting. The guideline of 50% serves as a benchmark to assess the adequacy of the stenting procedure and to inform any necessary follow-up interventions.
