Transcatheter occlusion of the left atrial appendage (LAA) for patients with non-valvular atrial fibrillation

Medical Services Advisory Committee
Record ID 32015000576
Authors' recomendations: The WATCHMANâ„¢ Left Atrial Appendage (LAA) Closure Device is intended for patients with non-valvular Atrial Fibrillation who require treatment for potential thrombus formation and are eligible for long-term oral anticoagulation therapy, or who have a contraindication to anticoagulation therapy. The procedure aims to prevent ischemic stroke and systemic thromboembolism by closing off the LAA permanently to avoid the migration of emboli (clots) to the brain. The LAA Closure Device is a self-expanding nitinol frame structure with fixation anchors and a permeable polyester fabric that covers the atrial facing surface of the device. The access sheath and delivery catheter permit device placement in the LAA via femoral venous access and inter-atrial septum crossing into the left atrium. The procedure takes up to approximately 60 minutes, and is performed under general anaesthesia by an interventional cardiologist or electrophysiologist in a catheterisation lab under fluoroscopy and transoesophageal echocardiogram (TOE).
