Summary
The Multi-Link Pixel stent is safe and effective for stenting small coronary arteries, even complex lesions. This study shows a low rate of target vessel revascularization in patients treated with this new stent.
Area of Science:
- Interventional Cardiology
- Cardiovascular Devices
- Vascular Surgery
Background:
- Limited data exist on stenting small coronary arteries.
- The Multi-Link Pixel stent is a novel device designed for small vessels (<2.5 mm).
Purpose of the Study:
- To prospectively evaluate the feasibility, safety, and efficacy of the Pixel coronary stent in small vessels.
- To assess outcomes in a multicenter Italian registry.
Main Methods:
- A registry of 231 patients (243 lesions) with small coronary arteries (<2.5 mm).
- High-risk patients included unstable angina, diabetes, and multivessel disease.
- Included complex lesions (B2/C, chronic total occlusions).
Main Results:
- Successful stent deployment in all lesions.
- Significant increase in minimal lumen diameter (0.71 to 2.32 mm) and decrease in stenosis (67.2% to 6.7%).
- Low rates of major adverse cardiac events (9.6% at 6 months) and target lesion revascularization (7.4% at 6 months).
Conclusions:
- The Multi-Link Pixel stent is safe and effective for complex coronary lesions in small vessels.
- The stent is associated with a low target vessel revascularization rate.
