ObjectiveTo describe the initial experience with Amplatzer Amulet in left atrial appendage occlusion in Slovakia. To evaluate procedural efficacy and safety.BackgroundAtrial fibrillation increases the risk of stroke. While anticoagulation therapy can reduce the risk of stroke, it is associated with bleeding risk and often unsatisfactory prescribed. Most thrombi form in the left atrium appendage, hence left atrium appendage occlusion may be a suitable therapeutic alternative for these patients.MethodsThis is an observational, retrospective, single-centre, case-series study including 30 patients with atrial fibrillation at a high risk of stroke, undergoing left atrial appendage occlusion from June 2015 to December 2018.ResultsThe left atrial appendage was successfully closed in 29 (96.7 %) patients. Three months after the procedure, 4 patients had small leaks (< 2 mm). No complications were reported so far. Prior to the procedure, patients mostly received low molecular weight heparin (53.3 %). Three months after the procedure, patients mostly received acetylsalicylic acid (60.7 %) and clopidogrel (32.1 %).ConclusionLeft atrial appendage occlusion was shown to be an effective and safe alternative to anticoagulation therapy in patients with atrial fibrillation, at a high risk of stroke and bleeding. The procedure is safe, when performed carefully even by less experienced cardiologists (Tab. 6, Fig. 4, Ref. 29).
