Routine stent placement in small coronary arteries yields good initial results but leads to high restenosis rates. Provisional stenting may be a better strategy, guided by imaging techniques for optimal intervention.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Research

Background:

  • Routine stent placement in small coronary arteries (<2.75-3.0 mm) shows high in-stent restenosis rates.
  • Randomized trials have not confirmed routine stenting as superior to balloon angioplasty in these vessels.

Purpose of the Study:

  • To describe the rationale for provisional stenting in small coronary arteries.
  • To review imaging modalities for guiding stent implantation in this setting.

Main Methods:

  • Review of existing data and randomized trials.
  • Discussion of quantitative coronary angiography, intracoronary ultrasound, and intracoronary Doppler.

Main Results:

  • Routine stenting offers good immediate outcomes but high long-term restenosis.

  • Provisional stenting is presented as a potentially superior strategy for small vessels.

    • Conclusions:

    • The optimal strategy for percutaneous coronary intervention in small arteries remains debated.
    • Imaging guidance is crucial for selecting lesions that benefit from stenting after balloon angioplasty.
