- Left atrial appendage occlusion (LAAO) is a treatment option for patients with atrial fibrillation (AF) who are at moderate to high risk of stroke and poor candidates for long-term anticoagulation1. LAAO lowers the risk of stroke by excluding the left atrial appendage from the systemic circulation and preventing thrombus formation and embolization1. LAA occlusion has emerged as an alternative for stroke prevention in patients with an elevated stroke risk who have appropriate rational for avoiding oral anticoagulation2. LAAO is a non-pharmacological option for preventing cardioembolic events in patients with non-valvular AF with a contraindication to OAT3.Learn more:✕This summary was generated using AI based on multiple online sources.

Nearly 40% of patients at risk of stroke thus do not receive any anticoagulation due to contraindication, bleeding, or patient/physician preferences. 3 Previous studies have reported that >90% of cardiac emboli in nonvalvular atrial fibrillation (NVAF) originate in the LAA. 4 LAA occlusion has thus emerged as an alternative for stroke prevention in such patients with an elevated stroke risk (based on CHADS 2 or more commonly...
