The eMESH 1 Feasibility Study


Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Atherosclerosis of Autologous Vein Coronary Artery Bypass Graft(s)
  • Age: Between 21 - 85 Years
  • Gender: Male or Female

Inclusion Criteria:

  • Randomized Cohort: Requires CABG surgery with a SVG to the right coronary artery (RCA) system AND the left circumflex artery (LCX) system with a 70% stenosis in each of the two systems.
  • Single Vessel Cohort: Requires CABG surgery with a SVG to the RCA system or the LCX system with a > 70% stenosis in the system.
  • Medial sternotomy with cardiopulmonary bypass (CPB) during surgery.
  • Both saphenous vein graft length are adequate for planned intervention, vein outer diameter is between 3.6 mm and 7.0 mm and double wall thickness less than 1.4 mm.
  • Agreement to post-procedure follow-up contact and testing (including follow-up coronary angiogram).

Exclusion Criteria:

  • Concomitant non-CABG cardiac procedure.
  • Prior cardiac surgery (does not include percutaneous procedures).
  • Cerebrovascular or transient ischemia attack within 30 days of the CABG procedure.
  • Age > 85 years.
  • Left ventricular ejection fraction 35%.
  • Creatinine > 133 mol/L (1.5 mg/dL) prior to CABG procedure or on chronic dialysis.
  • STEMI within 7 days or total CK > 2 times the upper limit of normal prior to the CABG procedure.
  • Both enrolled grafts will feed non-viable myocardial territory.
  • Diffuse atherosclerotic disease (> 70%) distal to either of the enrolled target coronary arteries.
  • Randomized Cohort: By visual estimate, the target coronary artery diameter of both the right coronary system and left circumflex system must be within 1.5mm of each other.
  • Planned endarterectomy of the target coronary artery.

Recruitment Status: Open
