Study of the PAS-Port® Proximal Anastomosis System in Coronary Bypass Surgery (EPIC)

This study has been completed.

The study has been designed to comparatively evaluate the safety and effectiveness of the PAS-Port Proximal Anastomosis System and conventional suturing techniques for creation of the connection between graft veins and the aorta in patients undergoing coronary artery bypass graft surgery for treatment of coronary artery disease. Patients in the study will have a coronary angiogram approximately 9 months following surgery to determine the patency of vein grafts created using either the automated PAS-Port or hand sewn methods. Safety will be evaluated by documenting the occurence of adverse clinical events and evealuating possible association with either method.

Exclusion Criteria:

  • Patient is participating in other clinical trials that would conflict with this protocol
  • Unable to meet study requirements (travel, general health)
  • Pregnancy
  • Previous cardiac surgery
  • Requiring preoperative use of an intraaortic balloon pump
  • Congestive heart failure / NYHA Class IV
  • History of thromboembolic disease requiring ongoing anticoagulation therapy or the presence of a bleeding disorder

Inclusion Criteria:

  • Patient is hemodynamically stable
  • Open chest reassessment of the revascularization strategy confirms that two vein bypass grafts are still intended
  • Target vessel wall properties that are suitable for performing both a hand-sewn and a PAS-Port anastomosis
  • Target vessel is greater than 1.8 mm in diameter at sites where anastomoses are planned
  • Target vessel at sites where anastomoses will be placed are free from severe calcifications or severe atheromas
  • The length of the vein graft(s) is adequate for both of the planned index graft revascularization strategies
  • Vein outside diameter and double wall thickness are between 4 and 6 mm(inclusive) and less than or equal to 1.4 mm, respectively, at the graft site intended for the PAS-Port proximal anastomosis
  • The vein(s) is of suitable quality to be used as a bypass graft conduit

Exclusion Criteria:

-Any of the Intra-operative Inclusion Criteria not met
