About this study

The study is To evaluate clinical and peri-procedural angiographic outcomes for the SYNERGYTM MONORAILTM Everolimus-Eluting Platinum Chromium Coronary Stent System in the treatment of subjects with atherosclerotic lesion(s) ≤34 mm in length (by visual estimate) in native coronary arteries ≥2.25 mm to ≤4.0 mm in diameter (by visual estimate).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Key Inclusion Criteria:

  • Subject must be at least 18 -75 years of age
  • Subject is eligible for percutaneous coronary intervention (PCI)
  • Target lesion(s) must be located in a native coronary artery with a visually estimated reference vessel diameter (RVD) ≥2.25 mm and ≤4.0 mm, length must be ≤34* mm (by visual estimate), Target lesion(s) must have visually estimated stenosis ≥50% and <100% with thrombolysis in Myocardial Infarction (TIMI) flow >1

Key Exclusion Criteria:

  • Planned PCI (including staged procedures) or CABG after the index procedure
  • Subject with out of range complete blood count (CBC) values that are determined by the study physician to be clinically significant.
  • Subject is on dialysis or has baseline serum creatinine level >2.0 mg/dL (177µmol/L)
  • Planned treatment of more than 3 lesions, Planned treatment of lesions in more than 2 major epicardial vessels, Planned treatment of a single lesion with more than 1 stent
  • Target lesion(s) 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.
  • Target vessel develops a dissection greater than National Heart, Lung, Blood Institute (NHLBI) type C following the pre-dilatation/pre-treatment of the first target lesion

Primary outcomes

  1. Technical Success Rate

    Time frame: 1 day

    Technical success rate, defined as successful delivery and deployment of the study stent to the target lesion, without balloon rupture or stent embolization, and post-procedure diameter stenosis of <30% assessed in 2 near-orthogonal projections with TIMI 3 flow in the target lesion, as visually assessed by the physician

Secondary outcomes

  1. Target Lesion Revascularization (TLR) Rate

    Time frame: 30 days

  2. Target Lesion Failure (TLF) Rate

    Time frame: 30 days

  3. Target Vessel Revascularization (TVR) Rate

    Time frame: 30 days

  4. Target Vessel Failure (TVF) Rate

    Time frame: 30 days

  5. Myocardial Infarction (MI, Q-wave and Non-Q-wave) Rate

    Time frame: 30 days
