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.

Secondary Outcomes (6)

  • Patency at 1 and 6 months

    1 month and 6 months.

  • Patency at 12 months

    12 months.

  • Lumen Diameter Uniformity

    12 months.

  • Immune Response

    12 months.

  • Device Serious Adverse Event (SAE)

    6 months, 12 months, 24 months, 48 months, and 60 months.

  • +1 more secondary outcomes

Study Arms (1)

ATEV with ESS

EXPERIMENTAL

Surgical implant of Acellular Tissue Engineered Vessel with External Support Structure as Coronary Artery bypass

Device: ATEV with ESS

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

Also known as: CABG
ATEV with ESS

Eligibility Criteria

Age45 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
