Transcatheter left atrial appendage occlusion in patients with atrial fibrillation

Atrial fibrillation is one of the most common cardiac arrhythmias. It affects 1-2% of the total population, and the frequency of its incidence increases with age. The threefold increase in the incidence of this disease is projected by 2050. In patients with atrial fibrillation there is a high risk of embolism in particular ischemic stroke. There are two main types of preventing the impact on the brain associated with occurrence of atrial fibrillation. The first is the use of chronic anticoagulant therapy, and the second is closing the left atrium appendage as a source of embolic material. The paper presents systems for transcatheter closing of the left atrial appendage in patients with atrial fibrillation. Describes the indications for this type of treatment and the results of available randomized trials.
