Summary
This study shows the STENTYS® self-expanding stent is effective for complex coronary artery disease, demonstrating high success rates and good long-term outcomes in patients with acute coronary syndromes and stable angina.
Area of Science:
- Interventional Cardiology
- Vascular Surgery
Background:
- Balloon-expandable stents are standard in coronary angioplasty.
- Complex cases like ectatic arteries, obscured lumens, or significant diameter variations pose challenges.
- Self-apposing stents, adapted from peripheral interventions, offer a potential solution.
Purpose of the Study:
- To evaluate the STENTYS® self-expanding stent in a single-centre registry.
- To assess its use in patients with acute coronary syndromes (ACS) or stable coronary artery disease (CAD).
Main Methods:
- A registry of 40 patients treated with STENTYS® self-expanding stents.
- Inclusion of patients with ACS or CAD.
- Follow-up included in-hospital, 30-day, and 12-month periods.
Main Results:
- Successful implantation in all 40 patients.
- Two in-hospital deaths in patients with cardiogenic shock and multivessel disease.
- No acute stent thrombosis or myocardial infarction.
- One case of ACS type 4b.
- Two procedural complications: distal dissection and proximal LAD dissection.
- 7.8% (3 patients) required target-lesion revascularization within 12 months.
Conclusions:
- STENTYS® stent demonstrated high delivery and procedural success rates.
- Satisfactory long-term clinical outcomes were observed in both stable and ACS patients.
- The stent design facilitated successful treatment of bifurcation lesions.
