Summary

Topical lubrication with Rotaglide aids stent delivery in complex coronary anatomy, proving safe and effective for percutaneous coronary interventions (PCI). This method improved procedural success and showed positive long-term clinical outcomes.

Area of Science:

  • Cardiovascular Interventions
  • Medical Device Technology
  • Clinical Outcomes Research

Background:

  • Failed stent delivery complicates up to 5% of percutaneous coronary interventions (PCI).
  • Complex coronary lesions present significant challenges for stent placement.

Purpose of the Study:

  • To evaluate the efficacy of topical lubrication in facilitating stent delivery in challenging coronary anatomy.
  • To assess the impact of topical lubrication on long-term clinical outcomes after PCI.

Main Methods:

  • A phospholipid emulsion (Rotaglide) was applied topically to stents after initial failed delivery attempts in 20 patients with complex lesions.
  • Stent delivery was reattempted following topical lubrication.
  • Procedural success and long-term clinical outcomes (follow-up 19.5 months) were assessed.

Main Results:

  • Successful stent deployment was achieved in 85% (17/20) of patients after topical lubrication.
  • No periprocedural complications or subacute stent thromboses were observed.
  • Among patients with drug-eluting stents, no instances of clinical restenosis or target vessel revascularization occurred.

Conclusions:

  • Topical lubrication with Rotaglide is a simple, effective method to improve stent delivery success in complex coronary lesions.
  • Rotaglide demonstrates safety and biocompatibility, particularly with drug-eluting stents, with favorable long-term clinical results.
