Initial Evaluation of Vascudyne Coronary Artery Bypass Conduit

Prior treatment

• Patients requiring emergency surgery.
• Patients with any prior open cardiac surgery such as coronary artery bypass graft (CABG).
• Any planned concomitant cardiac surgery, including but not limited to: valve surgery, repair of intracardiac shunt, surgical arrhythmia ablation.
• Treatment with any investigational drug or device within 60 days prior to study entry or ongoing participation in another clinical study of an investigational product.

Other illness

• 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.
• Moderate to severe chronic obstructive pulmonary disease (COPD) with a forced expiratory volume (FEV) \<1.5 lit/sec or 45% predicted forced expiratory volume in one second (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 (i.e. Warfarin) or any known intrinsic coagulation disorder.
• Known allergies to study device components: Nitinol, Nickel, Titanium, or agents/medication such as contrast agents, antiplatelet therapy, beta-blocker, or statins required for study assessment or optimal post-CABG medical treatment (hospital standard of care).
• Any medical intervention or condition within the 12 months following TRUE CAB implantation that requires temporary or permanent discontinuation of anticoagulant therapy.
• History of heparin-induced thrombocytopenia.
• Contraindication to or known serious allergy to anticoagulant, aspirin, or planned antiplatelet and factor Xa inhibitor therapy.
• Immunodeficiency including AIDS / HIV, active autoimmune disease, or on immunosuppressant therapy.
• Has any other condition, in the opinion of the principal investigator, which would put the patient at increased risk from participating in the study or otherwise prevent participation.

Lab values

• Patients with left ventricular ejection fraction \< 35%.
• Patients with Type 1 Diabetes and Patients with Type II Diabetes having glycate hemoglobin test (A1C)\>8.
• Chronic kidney disease with Glomerular Filtration Rate (GFR) \< 45 militers per minute (mL/min), or active dialysis patients
• Abnormal blood values (e.g. leukopenia, anemia, thrombocytopenia, or thrombocytosis with Platelet Count \>400,000 per militer (mL) that could influence graft hemostasis or patient recovery.

Other

• Patients with diffusely diseased coronary arteries suggestive of either poor target quality, or poor vessel runoff.
• Patients with cardiogenic shock.
• Subject has medical, social, or psychosocial factors that, in the opinion of the investigator, could impact safety or compliance.

• Patients needing isolated coronary artery bypass grafting to multiple coronary arteries (CA) in which the first target CA shall be an arterial bypass to the left anterior descending artery (LAD) and the second and potentially third target CA must be at least 2 mm in diameter, have at least 70% stenosis proximal to the bypass, have at least Thrombolysis in Myocardial Infarction (TIMI) II flow, and shall be among the following options: right coronary artery (RCA), right posterior descending artery (PDA), Ramus Intermedius, obtuse marginal arteries (OM), or diagonal branches of the left anterior descending artery.
• 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 CABG surgery.
• Life expectancy of at least 4 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 computerized tomography (CT) scan.
• Patient is willing to be compliant with prescribed anticoagulant therapy (critical to preventing thrombus in the investigational device).
