A Randomized, Multi-Center, Single-Blind Comparison of the Conor Cobalt Chromium Reservoir Based Stent with Sirolimus-Elution versus the TAXUS Liberte Paclitaxel-Eluting Coronary Stent System in De Novo Native Coronary Artery Lesions

INTERVENTION: Percutaneous coronary intervention for treatment of a single coronary lesion with implantation of a Conor Sirolimus‐eluting Coronary Stent. The coronary stenting procedure can take from one to two hours while the stent is a permanent implant. CONDITION: Coronary Atherosclerosis PRIMARY OUTCOME: Angiographic in‐stent late loss as measured by Quantitative Coronary Angiography. SECONDARY OUTCOME: Incidence of stent thrombosis Major adverse cardiac events Percent volume obstruction of the stent by intravascular ultrasound Target Lesion Failure Target Vessel Failure INCLUSION CRITERIA: The subject is eligible for percutaneous coronary intervention and coronary artery bypass graft surgery, The subject has a diagnosis of stable or unstable angina, or silent ischemia, The subject has a left ventricular ejection fraction >30%, The subject requires treatment of a single de novo lesion in a native coronary artery, The subject understands the study requriements, is willing to comply with all study procedures and has provided written informed consent.
