ABSTRACT

Background: Atrial fibrillation is the most frequent arrhythmia with a prevalence of 2% in the general population and is associated with a significantly increased risk of heart failure and thromboembolism, particularly stroke. In these patients, the left atrial appendage is the main site of thrombus formation. A pillar of the management of atrial fibrillation is anticoagulant therapy, but in patients who have absolute contraindications to anticoagulation, left atrial appendage occlusion devices are an alternative to reduce the risk of stroke. There are currently several occlusion devices that have a range of designs that adapt to the anatomy of the left atrial appendage of each patient.
Clinic case: A 96-year-old female patient with a history of atrial fibrillation and acute myocardial infarction in whom a transcatheter left atrial appendage occlusion device was successfully placed.
Conclusions: Left atrial appendage occlusion devices represent a viable and safe alternative for stroke prevention.
