Abstract:
The efficacy and safety of left atrial appendage occlusion (LAAO) in preventing non valvular atrial
fibrillation stroke have been confirmed by multiple randomized controlled and registered studies,and
have been recommended by several guidelines for stroke prevention in patients with atrial fibrillation at high risk of stroke.We reported an 80-year- old male patient with persistent atrial fibrillation Who have undergone LAAO surgery after admission. The second day after surgery with cardiac ultrasound indicating occluder displacement.Performed left atrial appendage occluder removal and LAAO on the same day,The patient have no discomfort and discharged five days after surgery.
Introduction Atrial fibrillation (AF) is a common atrial arrhythmia, associated with increased incidence rate and
mortality of cardiovascular events(1). AF is associated with an increased risk of thromboembolism
and stroke, requiring anticoagulation. Despite progress and development in anticoagulation strategies,
the high risk of bleeding complications and strict medication adherence make treatment more
complex.In the past few decades, left atrial appendage has become a promising therapeutic target,which can prevent thromboembolic events while reducing the problem of bleeding complications(2,3).Research has shown that left atrial appendage occlusion (LAAO) surgery is associated with a reduced incidence of cardiovascular events during hospitalization, and can also improve patient prognosis in long-term follow-up(4,5). In the past 20 years, among non valvular atrial fibrillation patients with increased risk of stroke, LAAO has become a safe and effective alternative to oral anticoagulants for stroke prevention(6).
