The procedure significantly reduces the risk of stroke and systemic embolism, which may render anticoagulation unnecessary or even harmful when considering the associated increased risk of bleeding. A clinical trial to address the need for anticoagulation after LAA closure is needed.\n\nThe ATLAAC trial will enroll 1220 patients with atrial fibrillation who have previously undergone surgical LAA closure. Patients will undergo a cardiac CT-scan to determine if LAA closure was successful and patients with successful closure will be randomized to continue or discontinue anticoagulation. The trial will assess the risk of ischemic stroke, peripheral arterial embolism, and major bleeding during the randomized intervention",[26,27,28],"Atrial Fibrillation","Left Atrial Appendage Absent","Anticoagulant Adverse Reaction",[30,31,32,33],"Atrial fibrillation","Anticoagulant treatment","Surgical left atrial appendage closure","surgical left atrial appendage occlusion","RECRUITING","2024-05-22",{"date":37,"type":38},"2024-05-23","ACTUAL",{"date":40,"type":38},"2024-05-21",{"date":42,"type":20},"2028-03",{"name":44,"class":45},"Odense University Hospital","OTHER",6]
