Outcome Measures
Primary Outcomes (2)
Successful implantation
Successful implantation as defined by meeting each of the following points: 1. Completion of both a proximal and distal anastomosis, 2. Placement of ESS, 3. No evidence of ATEV twist or kink on direct visual inspection.
30 days.
Freedom from Major Adverse Cardiac and Cerebrovascular events (MACCE) at 30 days.
Freedom from Major Adverse Cardiac and Cerebrovascular events (MACCE) at 30 days. MACCE is defined as combination of: 1. death, 2. non-fatal stroke, 3. non-fatal myocardial infarction, 4. unplanned revascularization 5. hospitalization due to heart failure
30 days.

Interventions
Patients will be implanted with a single Acellular Tissue Engineered Vessel with External Support Structure bypass (single proximal and distal anastomoses) to the second or third coronary artery bypass target
Eligibility Criteria
You may qualify if:
- Patient with limited quantity of good quality saphenous vein graft (SVG) for planned operation per the surgeon discretion.
- Bypass to at least three coronary arteries (CA); primary target shall be an Interior mesenteric artery (IMA) bypass to the Left anterior descending (LAD) artery, at least one SVG to a secondary CA target, and one Acellular Tissue Engineered Vessel (ATEV) to a secondary target CA that:
- requires ≤ 15cm long conduit
- has a diameter at least 1.5 mm at targeted landing site
- has at least 70% stenosis proximal to the target bypass
- has at least Thrombolysis in Myocardial Infarction (TIMI) flow grade II
- Male or female patients between the ages of 45 and 75 years inclusive.
- Elective patient, selected and accepted by the local Heart Team and confirmed by the Sponsor's Screening Committee for an on-pump full sternotomy coronary artery bypass grafting (CABG) surgery.
- Concomitant life-threatening disease likely to limit life expectancy to less than 2 years.
- Female subjects must be of non-childbearing potential, which is defined as post-menopausal (at least 1 year without menses prior to Screening) or documented surgically sterile or post hysterectomy (at least 1 month prior to Screening).
- Patient has been informed of the nature of the study, agrees to its provisions, and has provided written informed consent.
- Patient has been informed and agrees to pre- and post-procedure follow-up, including follow-up cardiac ultrasound and coronary angiogram or computed tomography (CT).
- Patient is willing to be compliant with prescribed anticoagulant therapy (critical to preventing thrombus in the ATEV).
You may not qualify if:
- Patients with left ventricular ejection fraction \< 35%.
- Patients with diffusely diseased coronary arteries suggestive of either poor target quality, or poor vessel runoff.
- Patients requiring emergency surgery.
- Patients with cardiogenic shock.
- Patients with any prior open cardiac surgery such as CABG.
- Any planned concomitant cardiac surgery, including but not limited to: valve surgery, repair of intracardiac shunt, surgical arrhythmia ablation.
- History of cardiac resynchronization therapy (CRT) or implantable cardioverter defibrillator (ICD) implantation.
- Myocardial infarction (MI) within 21 days or cerebral vascular accident (CVA) within 90 days of the CABG procedure.
- Patient with uncontrolled diabetes (glycated hemoglobin \> 8%).
- Chronic Kidney Disease (CKD) with Glomerular Filtration Rate (GFR) \<45 mL/min/1.73m2 (Category: G3b-G5 according to Kidney Disease: Improving Global Outcomes (KDIGO)).
- Moderate to severe chronic obstructive pulmonary disease (COPD) with a forced expiratory volume (FEV) \<1.5 L/sec or 45% predicted FEV1.
- Patient with known interstitial lung disease, diagnosed by imaging or pulmonary function tests, including Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO).
- Endocarditis, pericarditis, or any other active systemic infection that would interfere with patient safety.
- Patient on preoperative anticoagulant, or pre existing indication for anticoagulation (e.g. atrial fibrillation, history of thromboembolism), or with known coagulation disorder.
- Abnormal blood values (e.g. leukopenia, anemia, thrombocytopenia, or thrombocytosis with Platelet Count \>400,000 per mL that could influence graft hemostasis or patient recovery
