Stenting without predilatation (SWOP) is a feasible and effective strategy for approximately 60% of lesions when primary stenting is planned. This approach yields excellent procedural results and offers significant cost savings in interventional cardiology.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Interventions
  • Medical Device Technology

Background:

  • Coronary artery interventions commonly involve balloon angioplasty and stenting.
  • Predilatation is a standard step in many stenting procedures.
  • Evaluating alternative strategies like stenting without predilatation is crucial for optimizing patient care and resource utilization.

Purpose of the Study:

  • To assess the feasibility and procedural success of stenting without predilatation (SWOP) compared to other interventional strategies.
  • To determine the proportion of lesions suitable for SWOP.
  • To evaluate the cost-effectiveness implications of SWOP.

Main Methods:

  • A prospective registration of 684 interventional procedures across 600 patients over a 6-month period.

  • Interventions were categorized into four groups: SWOP, primary stenting with predilatation (PDS), provisional stenting (PRS), and plain-old balloon angioplasty (POBA).
  • Interventional strategy selection was based on operator discretion, angiographic criteria, and clinical judgment.

    • Main Results:

    • SWOP was utilized in 32.4% of lesions (221/684).
    • Procedural success rates were comparable across all stenting groups (SWOP, PDS, PRS).
    • Approximately 60% of lesions planned for primary stenting were effectively treated with SWOP.

    Conclusions:

    • Stenting without predilatation (SWOP) is a viable and effective strategy for a significant proportion of coronary lesions.
    • SWOP demonstrates excellent procedural results, comparable to predilatation techniques.
    • Implementing SWOP when primary stenting is indicated can lead to considerable cost savings in interventional cardiology procedures.
