Primary Outcome Measures:
  • Acute Safety [ Time Frame: Randomization until Hospital Discharge ] [ Designated as safety issue: Yes ]
    An analysis comparing the rate of procedure related serious adverse events that occur in the device arm to a performance goal determined from literature reported rates for similar procedural techniques.

  • Long-term safety [ Time Frame: Randomization to 2 year follow-up ] [ Designated as safety issue: Yes ]
    An analysis comparing safety events (all-cause death and major bleeding) that occur between the device arm and the control arm.

  • Effectiveness endpoint [ Time Frame: Randomization through 2 year follow up ] [ Designated as safety issue: No ]
    Occurrence of ischemic stroke and peripheral thromboembolism


Secondary Outcome Measures:
  • Acute clinical success [ Time Frame: In-hospital to 45 days post procedure ] [ Designated as safety issue: Yes ]
    No reported in-hospital serious adverse events, closure of LAA documented at Day 45 TEE, no ischemic stroke or peripheral thromboembolism and discontinuation of warfarin or dabigatran.

  • Long-term clinical success [ Time Frame: Implant to at least 6 months follow-up ] [ Designated as safety issue: Yes ]
    No reported in-hospital serious adverse events, closure of LAA documented at Day 45 TEE, no ischemic stroke or peripheral thromboembolism and sustained discontinuation of warfarin or dabigatran at last available follow-up.

  • Adverse Events [ Time Frame: Randomization through required follow-ups ] [ Designated as safety issue: Yes ]

    Assessing adverse events:

    • Device embolization
    • Myocardial perforation (hemopericardium) or any pericardial effusion requiring drainage
    • Endocarditis
    • Thrombus on device
    • Asymptomatic intracerebral or intraventricular hemorrhage
    • Transient Ischemic Attack

  • Atrial Fibrillation Status [ Time Frame: Randomization through required follow-ups ] [ Designated as safety issue: No ]
    Subjects who progress from paroxysmal to persistent AF or subjects who progress from persistent to permanent AF.

  • Technical success [ Time Frame: Procedure ] [ Designated as safety issue: No ]
    Delivery and release of the ACP device, including recapture and/or replacement, as necessary.

  • Complete Closure [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Absence of flow into the LAA as assessed by TEE at 6 months.
