Eligibility

Min Age: 18 Years

Inclusion Criteria9

  • Subject must be at least 18 years of age.
  • Subject or a legally authorized representative must be able to provide written Informed Consent prior to any study related procedure, per site requirements.
  • Subject must have evidence of myocardial ischemia (e.g., stable angina, silent ischemia, unstable angina, acute myocardial infarction) suitable for elective PCI.
  • Subject must be an acceptable candidate for coronary artery bypass graft (CABG) surgery.
  • Subject must be able to take dual antiplatelet therapy (DAPT) for minimum of 12 months following the index procedure and anticoagulants prior/during the index procedure, and the subject has no known allergic reaction, hypersensitivity or contraindication to aspirin, clopidogrel, prasugrel, ticagrelor, ticlopidine or heparin.
  • Female subjects of childbearing potential must not be pregnant\* at screening and do not plan pregnancy for at least 12 months following the index procedure.
  • \* Female subjects of child-bearing potential must have a negative pregnancy result within 7 days prior to the index procedure.
  • Female subjects must not be breast-feeding at the time of the screening visit and will not be breast-feeding for at least 12 months following the index procedure.
  • Subject agrees to not participate in any other investigational or invasive clinical study for a period of 13 months following the index procedure.

Exclusion Criteria33

  • Elective surgery planned within 12 months after the procedure that will require general anesthesia or discontinuing either aspirin or P2Y12 inhibitor.
  • Subject has known hypersensitivity or contraindication to device material and its degradants (everolimus, PLLA, PDLLA, platinum, lactic acid, and lactide) that cannot be adequately pre-medicated.
  • Subject has a known contrast sensitivity that cannot be adequately pre-medicated.
  • Subject with known diagnosis of ST-elevation myocardial infarction (STEMI) within 72 hours of the index procedure.
  • The subject is currently experiencing clinical symptoms consistent with new onset acute myocardial infarction (AMI), such as nitrate-unresponsive prolonged chest pain with ischemic ECG changes.
  • Subject has an unstable cardiac arrhythmia which is likely to become hemodynamically unstable due to their arrhythmia
  • Subject has a known left ventricular ejection fraction (LVEF) \< 30% (LVEF may be obtained at the time of the index procedure prior to subject registration if the value is unknown and the site Investigator believes it is necessary).
  • The target vessel was treated by PCI within 12 months prior to index procedure.
  • Prior PCI within the non-target vessel is acceptable if performed anytime \> 30 days before the index procedure, or between 24 hours and 30 days before the index procedure if successful and uncomplicated.
  • Subject requires future staged PCI either in target or non-target vessels.
  • Subject has a malignancy that is not in remission.
  • Subject is receiving immunosuppressant therapy or has known life-threatening immunosuppressive or life-threatening autoimmune disease (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.). Note: corticosteroids are not included as immunosuppressant therapy, diabetes mellitus is not regarded as autoimmune disease.
  • Subject has received any solid organ transplants or is on a waiting list for any solid organ transplants.
  • Subject has previously received or scheduled to receive radiotherapy to coronary artery (brachytherapy), or chest/mediastinum.
  • Subject is receiving or will require chronic anticoagulation therapy (e.g., warfarin).
  • Subject has a platelet count \< 100,000 cells/mm3 or \> 700,000 cells/mm3.
  • Subject has documented or suspected cirrhosis of Child-Pugh ≥ Class B.
  • Subject has known renal insufficiency:
  • Dialysis at the time of screening or
  • An estimated GFR \< 30 ml/min/1.73m2
  • Subject has a high risk of bleeding, or;
  • Subject has a history of bleeding diathesis or coagulopathy.
  • Subject has had a significant gastro-intestinal or significant urinary bleed within the past six months.
  • Subject has prior intracranial bleed (including severe permanent neurologic deficit that seems to be caused by previous intracranial bleeding).
  • Subject has known intracranial pathology that may cause intracranial bleeding per investigator assessment (e.g., untreated aneurysm greater than 5 mm, arteriovenous malformation)
  • Subject will refuse blood transfusions.
  • Subject is receiving antiplatelet medication other than aspirin or P2Y12 inhibitor for the treatment of another condition and cannot discontinue them
  • Subject has had a cerebrovascular accident or transient ischemic neurological attack (TIA) within the past six months,
  • Subject has extensive peripheral vascular disease that precludes safe 6 French sheath insertion via any vessel.
  • Subject has life expectancy \< 3 years.
  • Subject is in the opinion of the Investigator or designee, unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason.
  • Subject is currently participating in another clinical trial that has not yet completed its primary endpoint.
  • Subject whose willingness to volunteer in a clinical investigation could be unduly influenced by the expectation, whether justified or not, of benefits associated with participation or of retaliatory response from senior members of a hierarchy in case of refusal to participate (e.g., subordinate hospital staff or sponsor staff).
