The primary effectiveness outcome is the percentage of patients with complete exclusion of the left atrial appendage assessed peri-operatively (visually), and at 90 days post procedure via transesophageal echocardiography (TEE).\n\nTransesophageal echocardiography will be performed intra-operatively and again at 90 days post procedure. Intra-operative and follow-up TEE examinations will be read centrally at a core laboratory. Any Doppler flow across the Fastener into the excluded portion of the appendage will also be considered a failure of exclusion. The presence or absence of LAA and/or LA thrombus will be evaluated. Patients will also be evaluated for other potential sources of embolism, including aortic atheroma, patent foramen ovale, or other intracardiac shunts.\n\nData collection will be completed at baseline, at the time of open cardiac surgery procedure and throughout the perioperative hospitalization. Patients will be evaluated at 30 days post surgery and at 90 days post surgery.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
