Left atrial appendage occlusion for atrial fibrillation and bleeding diathesis.

Background: Patients with atrial fibrillation (AF) and likelihood of bleeding can undergo left atrial appendage occlusion (LAAO) as an alternative method of stroke prophylaxis. Short-term anti-thrombotic drugs are used postprocedure to offset the risk of device-related thrombus, evidence for this practice is limited.

Objectives: To investigate optimal postimplant antithrombotic strategy in high bleeding-risk patients.
