Brief Summary:
The purpose of this study is to assess the safety and effectiveness of the SYNERGY™ Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) ≤ 34 mm in length (by visual estimate) in native coronary arteries ≥2.25 mm to ≤4.0 mm in diameter (by visual estimate)

Coronary Artery Disease Device: SYNERGY Investigational Device Device: PE Plus Investigational Device Not Applicable

Detailed Description:

The EVOLVE China clinical trial is designed to assess the safety and effectiveness of the SYNERGY™ Everolimus-Eluting Platinum Chromium Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) in native coronary arteries in China. The SYNERGY™ Stent System (Boston Scientific Corporation [BSC Corporation], Natick, Massachusetts, United States) is based on the well characterized Element™ stent platform and utilizes a bioabsorbable poly(DL-lactide-co-glycolide) (PLGA) polymer to deliver everolimus.

While SYNERGY is a new generation DES, the safety and effectiveness of the Element stent platform in combination with everolimus in the form of the PROMUS Element stent has been established in the PLATINUM Clinical Trial Program.The PROMUS Element Plus stent (control device) uses the same stent platform as PROMUS Element stent with a modified balloon component on the Stent Delivery System to improve overall system deliverability. In addition, the previous version of the SYNERGY stent, the SYNERGY First Human Use stent (SYNERGY FHU stent) has been investigated in the EVOLVE FHU trial which has completed its primary endpoint and demonstrated comparable safety and efficacy profile of SYNERGY FHU to PROMUS Element up to 1-year follow-up (28). SYNERGY has been approved by CE Mark.

Primary Outcome Measures :
  1. The In-stent Late Loss Measured by Quantitative Coronary Angiography [ Time Frame: at 9 months post-index procedure. ]

Secondary Outcome Measures :
  1. Target Lesion Revascularization (TLR) Rate [ Time Frame: 12 months post-index procedure ]
    Target lesion revascularization is any ischemia-driven repeat percutaneous intervention, to improve blood flow, of the successfully treated target lesion or bypass surgery of the target vessel with a graft distally to the successfully treated target lesion.


Other Outcome Measures:
  1. Target Lesion Failure (TLF) Rate [ Time Frame: 12 months post-index procedure ]
    Target lesion failure is any ischemia-driven revascularization of the target lesion, MI (Q-wave and non-Q-wave) related to the target vessel, or (cardiac) death.
