Brief Summary:
The purpose of the TAXUS PERSEUS Small Vessel trial is to evaluate the safety and efficacy of the next-generation Boston Scientific TAXUS paclitaxel-eluting coronary stent system (TAXUS® ElementTM) for the treatment of de novo atherosclerotic lesions of up to 20 mm in length in native coronary arteries of ≥ 2.25 mm to < 2.75 mm diameter.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: Percutaneous Coronary Intervention (PCI) with paclitaxel-eluting stent (TAXUS Element) implantation Phase 3

Detailed Description:

This is a prospective, multi-center, single-arm superiority trial to assess the TAXUS® Element™ Paclitaxel-Eluting Coronary Stent System for the treatment of de novo atherosclerotic lesions of ≤20 mm in length in native coronary arteries with visual RVD of ≥ 2.25 mm to < 2.75 mm diameter.

Two hundred twenty-four (224) subjects will be treated with the TAXUS Element stent at a maximum of 35 clinical sites. Follow-up at 30 days, 9 months including angiography) and 1 year will be completed in all subjects enrolled in the study. Eligible subjects will have annual follow-up until 5 years post-index procedure.

Primary Outcome Measures :
  1. In-stent Late Loss Measured by Quantitative Coronary Angiography (QCA) [ Time Frame: 9 months post-index procedure ]
    Post-procedure minimum lumen diameter (mm) minus follow-up minimum lumen diameter as determined by quantitative angiography. Minimum lumen diameter is measured within the stent at each time point.

Secondary Outcome Measures :
  1. Number of Participants With Target Lesion Failure (TLF) at 12 Months Post-index Procedure. TLF is Defined as Any Ischemia-driven Revascularization of the Target Lesion, Myocardial Infarction (Q-wave and Non-Q-wave), or Death Related to the Target Vessel. [ Time Frame: 12 months post-index procedure ]
    The number of participants who experience a TLF through 365 days post-procedure out of the patients who have either had a TLF within 365 days post-procedure or who were TLF-free with last follow-up at least 335 days post-procedure.
