  Purpose

This is a multi-center, prospective, randomized and controlled clinical trial comparing the safety and efficacy of the CorMatrix ECM for Pericardial Closure to reduce the incidence of new onset postoperative atrial fibrillation by circumferentially reconstructing the normal pericardial anatomy following isolated, first-time, CABG procedures compared to subjects that do not undergo pericardial closure. This trial will be conducted at up to 20 clinical sites in the U.S.

Primary Outcome Measures:
  • Primary Safety Endpoint [ Time Frame: 30 days postprocedure ] [ Designated as safety issue: Yes ]
    A composite endpoint consisting of procedure-related serious adverse events occurring within 30 days postprocedure.

  • Primary Effectiveness Endpoint [ Time Frame: 7 days postoperatively or hospital discharge, whichever is sooner ] [ Designated as safety issue: No ]
    Rate of new onset postoperative atrial fibrillation during the first seven days postoperatively or prior hospital discharge, whichever is sooner.


Secondary Outcome Measures:
  • Secondary Safety Endpoint [ Time Frame: 270 days postprocedure ] [ Designated as safety issue: Yes ]
    A composite measure of bypass graft failure consisting of procedure-related events occurring beyond 30 days and within 270 days postprocedure.

  • Secondary Effectiveness Endpoint [ Time Frame: 7 days postoperatively or hospital discharge, whichever is sooner ] [ Designated as safety issue: No ]
    Rate of treated or sustained episodes of new onset postoperative atrial fibrillation during the first seven days postoperatively or prior to hospital discharge, whichever is sooner.

  • Secondary Effectiveness Endpoint [ Time Frame: 7 days postoperatively or hospital discharge, whichever is sooner ] [ Designated as safety issue: No ]
    Rate of treated episodes of new onset postoperative atrial fibrillation during the first seven days postoperatively or prior to hospital discharge, whichever is sooner.

Arms Assigned Interventions
Experimental: CorMatrix® ECM® Device: CorMatrix® ECM® for Pericardial Closure
Circumferential closure of the pericardium following CABG surgery using the CorMatrix ECM for Pericardial Closure
No Intervention: No Pericardial Closure

Detailed Description:

The objective of this prospective clinical trial is to demonstrate the safety and efficacy of the CorMatrix ECM for Pericardial Closure to reduce the incidence of new onset postoperative atrial fibrillation by circumferentially reconstructing the normal pericardial anatomy following isolated, first-time, coronary artery bypass grafting (CABG) procedures as compared to subjects who did not undergo pericardial closure. Safety will be established by demonstrating that the composite clinical event rate for the ECM treatment group is not worse than the control group that did not undergo pericardial closure. The efficacy will be established by demonstrating a reduced incidence of new onset postoperative atrial fibrillation in the ECM treatment group as compared to the control group.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • The subject is 18 years of age or older
  • This cardiac operation is the subject's first or primary cardiac operation
  • The subject must be undergoing an isolated CABG procedure using a median sternotomy approach
  • The subject must possess the ability to provide written Informed Consent
  • The subject must express a willingness to fulfill all of the expected requirements of this clinical protocol

Exclusion Criteria:

  • Prior history of atrial fibrillation
  • Prior history of open heart surgery
  • Prior history of pericarditis
  • Prior history of anti-arrhythmia drug treatment (e.g., amiodarone, dronedarone or sotalol) in the past six months
  • The subject has an implantable cardiac device (i.e., cardiac resynchronization therapy devices with and without defibrillator capabilities (CRTs and CRT-Ds), implantable cardioverter-defibrillators (ICD) and pacemakers)
  • Concomitant procedure planned
  • In the investigator's opinion, the subject may require prophylactic treatment with anti-arrhythmia drugs or temporary pacing postoperatively
