NCT03209609

Brief Summary

Prospective, multi-center, randomized, within-subject-controlled , trial, enrolling patients with multi vessel atherosclerotic coronary artery disease, scheduled to undergo SVG CABG with arterial grafting of IMA to LAD and two or more saphenous vein grafts. In each patient, one SVG bypass will be randomized to be supported by the VEST, while another will not be supported and serve as control. Thus, the full cohort will provide a basis for comparison between two sets of SVGs: A VEST supported set; and an unsupported set.

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Signed informed consent, inclusive of release of medical information, and Health Insurance Portability and Accountability Act (HIPAA) documentation.
  • Age 21 years or older.
  • Planned and scheduled on-pump CABG.
  • Two or more vein grafts to native vessels having at least 75% stenosis and comparable runoff.
  • IMA graft indicated for the LAD. Additional arterial grafts may be considered based on practice guidelines.
  • Appropriately sized and accessible target coronary arteries, with a minimum diameter of 1.5 mm and adequate vascular bed (without significant distal stenosis), as assessed by pre-operative cardiac angiography and verified by diameter gauging intraoperatively.

You may not qualify if:

  • Concomitant non-CABG cardiac surgical procedure.
  • Prior cardiac surgery.
  • Emergency CABG surgery.
  • Contraindication for on-pump CABG with cardioplegic arrest (e.g. severely calcified aorta).
  • Calcification at the intended anastomotic sites, as assessed upon opening of the chest and before randomization.
  • Severe vein varicosity as assessed after vein harvesting and before randomization.
  • History of clinical stroke within 3 months prior to randomization.
  • Severe renal dysfunction (Cr\>2.0 mg/dL).
  • Documented or suspected untreated diffuse peripheral vascular disease such as: carotid stenosis or claudication of the extremities.
  • Concomitant life-threatening disease likely to limit life expectancy to less than two years.
  • Inability to tolerate or comply with required guideline-based post-operative drug regimen (antiplatelet plus statin) and/or inability to take aspirin.
  • Inability to comply with required follow-ups including angiographic imaging methods (e.g. contrast allergy).
  • Concurrent participation in an interventional (drug or device) trial.
