Abstract
: Atrial fibrillation is the most common cardiac arrhythmia and its prevalence is constantly increasing. The main complications related to atrial fibrillation are death and major stroke. Oral anticoagulant therapy is the cornerstone of management of atrial fibrillation patients at increased stroke risk. Unfortunately, a significant proportion of patients do not receive adequate anticoagulant therapy due to increased or prohibitive hemorrhagic risk. The observation that most thrombi are generated in the left atrial appendage (LAA) had led to the consideration of surgical or percutaneous occlusion as an alternative. During recent years, the WATCHMAN percutaneous occlusion device has proven to be not inferior to anticoagulant therapy for the prevention of thromboembolic events, with the added benefit of a lower rate of hemorrhagic events. Numerous data showed the same results for the AMPLATZER cardiac plug and Amulet devices. Left atrial appendage occlusion (LAAO) often represents the only therapeutic strategy in this group of patients. We describe the current state of the art of percutaneous LAAO in atrial fibrillation patients with a high hemorrhagic risk.
