Self-expanding stent for complex percutaneous coronary interventions: A real life experience

Area of Science:

• Interventional Cardiology
• Biomedical Engineering
• Vascular Devices

Background:

• Self-expanding stents are emerging as a viable option for percutaneous coronary interventions.
• Their utility spans complex angiographic scenarios including coronary bifurcations, acute coronary syndromes with high thrombotic burden, and ectatic coronary stenosis.

Purpose of the Study:

• To review the clinical experience with self-expanding STENTYS® stents.
• To evaluate their efficacy and safety in diverse clinical and angiographic indications with long-term follow-up.

Main Methods:

• A retrospective analysis of 40 consecutive patients treated with STENTYS® stents (2011-2013).
• Outcomes assessed included all-cause and cardiovascular death, myocardial infarction, target lesion revascularization (TLR), and stent thrombosis.
• Comparison with conventional stents used in similar clinical/angiographic situations during the same period.

Main Results:

• STENTYS® stents were used in coronary bifurcations (55%), acute coronary syndromes (35%), and ectatic coronaries (15%).
• Acute stent thrombosis occurred in 2.5% of patients (similar to the control group).
• Target lesion revascularization due to stent restenosis occurred in 5% of patients (compared to 6.25% in the control group).

Conclusions:

• Self-expanding STENTYS® stents are effective in various complex angiographic situations.
• They offer a favorable safety profile with low complication rates.
• These stents represent a valuable alternative to balloon-expandable stents, with good long-term clinical outcomes.
