The Bard XT stent, a new balloon-expandable intracoronary device, showed high success rates in delivering and achieving angiographic results in 93 patients. Further research is needed to assess its long-term impact on restenosis.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Biomedical Engineering

Background:

  • The Bard XT stent represents a new generation of balloon-expandable intracoronary stents.
  • It features unique design advantages aimed at improving deployment and outcomes.

Purpose of the Study:

  • To evaluate the safety and efficacy of the Bard XT stent in patients undergoing coronary interventions.
  • To assess angiographic success, procedural success, and short-term clinical outcomes.

Main Methods:

  • A prospective study involving 93 patients with 109 coronary lesions treated with 127 Bard XT stents.
  • Lesions were classified according to the American College of Cardiology/American Heart Association (ACC/AHA) criteria.
  • Angiographic and procedural success rates, changes in minimal luminal diameter (MLD), and stenosis reduction were measured.

Main Results:

  • Stent delivery success rate was 98%, with 98% angiographic success and 94% procedural success.
  • Significant improvement in MLD (0.91 to 3.03 mm) and reduction in stenosis (69.1% to 9.96%) were observed.
  • Four complications occurred, including one intracranial hemorrhage, one subacute thrombosis, and two postprocedure deaths.

Conclusions:

  • The Bard XT stent is a user-friendly device demonstrating excellent short-term angiographic results and clinical outcomes in selected patients.
  • Further investigation is warranted to determine the long-term effects of the Bard XT stent on restenosis rates.
