Introduction
Left atrial appendage occlusion (LAAO) is an alternative to oral
anticoagulants for prevention of stroke in patients with atrial
fibrillation who are not optimal candidates for long-term
anticoagulation. Acute thrombus formation on the delivery sheath during
left atrial appendage occlusion is rare condition. Periprocedural stroke
during LAAO is extremely unacceptable. We described the use of placement
of cerebral embolic protection devices to prevent neurological events
when acute thrombus formation during the implantation of LACbes
(Shanghai PushMed, Shanghai, China).
