A Clinical Trial to Assess the SYNERGY 48 mm Stent System for the Treatment of Atherosclerotic Lesion(s)

Clinical Inclusion Criteria * Subject must be at least 18 years of age * Subject (or legal guardian) understands the trial requirements and the treatment procedures and provides written informed consent before any trial-specific tests or procedures are performed * Subject is eligible for percutaneous coronary intervention (PCI) and is an acceptable candidate for coronary artery bypass grafting (CABG) * Subject has either: * Symptomatic coronary artery disease with one of the following: stenosis ≥ 70%, abnormal fractional flow reserve (FFR), abnormal stress or imaging stress test, or elevated biomarkers prior to the procedure * OR * Documented silent ischemia based on one of the following: abnormal fractional flow reserve (FFR), abnormal stress or imaging stress test, or elevated biomarkers prior to the procedure * Subject is willing to comply with all protocol-required follow-up evaluation Angiographic Inclusion Criteria (visual estimate) * Target lesion must be located in a native coronary artery with a visually estimated reference vessel diameter (RVD) ≥2.5 mm and ≤4.0 mm * Target lesion length must be \>34 mm and ≤44 mm (by visual estimate) * Target lesion must have visually estimated stenosis ≥50% and \<100% with thrombolysis in Myocardial Infarction (TIMI) flow \>1 * Coronary anatomy is likely to allow delivery of a study device to the target lesion * The target lesion must be successfully predilated/pretreated. If a non-target lesion is treated, it should be treated first and should be deemed an angiographic success Note: Angiographic success is a mean lesion diameter stenosis \< 50% (\< 30% for stents) in 2 near-orthogonal projections with TIMI 3 flow, as visually assessed by the physician, without the occurrence of prolonged chest pain or ECG changes consistent with MI. Note: Successful predilatation/pretreatment refers to dilatation with a balloon catheter of appropriate length and diameter, or pretreatment with directional or rotational coronary atherectomy, laser or cutting/scoring balloon with no greater than 50% residual stenosis and no dissection greater than National Heart, Lung, Blood Institute (NHLBI) type C. Clinical Exclusion Criteria * Subject has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute ST elevation MI (STEMI) * Subject has cardiogenic shock, hemodynamic instability requiring inotropic or mechanical circulatory support, intractable ventricular arrhythmias, or ongoing intractable angina * Subject has received an organ transplant or is on a waiting list for an organ transplant * Subject is receiving or scheduled to receive chemotherapy within 30 days before or after the index procedure * Planned PCI (including staged procedures) or CABG after the index procedure * Subject previously treated at any time with intravascular brachytherapy * Subject has a known allergy to contrast (that cannot be adequately premedicated) and/or the trial stent system or protocol-required concomitant medications (e.g., platinum, platinum-chromium alloy, stainless steel, everolimus or structurally related compounds, polymer or individual components, all P2Y12 inhibitors, or aspirin) * Subject has one of the following (as assessed prior to enrollment): * Other serious medical illness (e.g., cancer, congestive heart failure) with estimated life expectancy of less than 24 months * Current problems with substance abuse (e.g., alcohol, cocaine, heroin, etc.) * Planned procedure that may cause non-compliance with the protocol or confound data interpretation * Subject is receiving chronic (≥72 hours) anticoagulation therapy (i.e., heparin, coumadin) for indications other than acute coronary syndrome * Subject has a platelet count \<100,000 cells/mm3 or \>700,000 cells/mm3 * Subject has a white blood cell (WBC) count \< 3,000 cells/mm3 * Subject has documented or suspected liver disease, including laboratory evidence of hepatitis * Subject is on dialysis or has baseline serum creatinine level \>2.0 mg/dL (177µmol/L) * Subject has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions * Subject has had a history of cerebrovascular accident (CVA) or transient ischemic attack (TIA) within the past 6 months * Subject has an active peptic ulcer or active gastrointestinal (GI) bleeding * Subject has signs or symptoms of active heart failure (i.e., New York Heart Association (NYHA) class IV) at the time of the index procedure * Subject is participating in another investigational drug or device clinical trial that has not reached its primary endpoint * Subject intends to participate in another investigational drug or device clinical trial within 12 months after the index procedure * Subject with known intention to procreate within 12 months after the index procedure (women of child-bearing potential who are sexually active must agree to use a reliable method of contraception from the time of screening through 12 months after the index procedure) * Subject is a woman who is pregnant or nursing Angiographic Exclusion Criteria (visual estimate) * Subject has more than 1 target lesion, or more than 1 target lesion and 1 non-target lesion, which will be treated during the index procedure Note: Multiple focal stenoses will be considered as a single lesion if they can be completely covered with 1 study stent * Treatment of lesions in more than 2 major epicardial vessels Note: 1 target lesion in the target vessel and 1 non-target lesion in non-target vessel is allowed * Subject has unprotected left main coronary artery disease (\>50% diameter stenosis) * Subject has been treated with any type of PCI (i.e., balloon angioplasty, stent, cutting balloon atherectomy) within 24 hours prior to the index procedure * Thrombus, or possible thrombus, present in the target vessel (by visual estimate) * Target lesion meets any of the following criteria: * Treatment of a single lesion with more than 1 stent * Left main location * Lesion is located within 3 mm of the origin of the left anterior descending (LAD) coronary artery or left circumflex (LCx) coronary artery by visual estimate * Lesion is located within a saphenous vein graft or an arterial graft * Lesion will be accessed via a saphenous vein graft or arterial graft * Lesion with a TIMI flow 0 (total occlusion) or TIMI flow 1 prior to guide wire crossing * Lesion treated during the index procedure that involves a complex bifurcation (e.g., bifurcation lesion requiring treatment with more than 1 stent) * Lesion is restenotic from a previous stent implantation or study stent would overlap with a previous stent * Non-target lesion meets any of the following criteria: * Located within the target vessel * Left main location * Lesion is located within a saphenous vein graft or an arterial graft * Lesion with a TIMI flow 0 (total occlusion) or TIMI flow 1 prior to guide wire crossing * Lesion treated during the index procedure that involves a complex bifurcation (e.g., bifurcation lesion requiring treatment with more than 1 stent) * Requires additional unplanned stents (treatment of the non-target lesion with more than one stent is permitted as long as the stents are initially planned) * Treatment not deemed an angiographic success Note: Angiographic success is a mean lesion diameter stenosis \< 50% (\< 30% for stents) in 2 near-orthogonal projections with TIMI 3 flow, as visually assessed by the physician, without the occurrence of prolonged chest pain or ECG changes consistent with MI.
