ABSTRACT

Stroke is the complication of atrial fibrillation with the greatest social and economic impact. The prevalence of this arrhythmia is epidemically growing. Although oral anticoagulants are highly effective, their contraindications, hemorrhagic complications and non-compliance of patients result in underutilization of this therapy. This review addresses aspects related to endocardial occlusion of the left atrial appendage as an alternative strategy to antithrombotic therapy, ranging from the introduction of the technique in clinical practice, the new devices being developed, technical peculiarities, and economic aspects, to uncertainties related to the intervention.
