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).
