Atrial Appendage
Registry data show lower event rates vs. trial data for LAA closure device
Patients with atrial fibrillation who underwent left atrial appendage occlusion with an FDA-approved device had lower rates of major in-hospital adverse events compared with previous trials assessing the device, according to data presented at the virtual American College of Cardiology Scientific Session.
Oral anticoagulation contraindication, increased mortality risk more likely in older patients with AF
Older patients with atrial fibrillation were more likely to have high bleeding risk contraindications with oral anticoagulation and higher mortality compared with patients who were not treated with oral anticoagulation and did not have contraindications, according to a observational, longitudinal analysis published in JACC: Clinical Electrophysiology.
Stroke risk increases after electrical LAA isolation
Electrical isolation of the left atrial appendage increased the risk for stroke, which can be reduced with left atrial appendage occlusion or uninterrupted oral anticoagulation, according to a study published in the Journal of the American College of Cardiology.
Operator experience not tied to outcomes after left atrial appendage occlusion
In a single-center study, there was no difference in outcomes after left atrial appendage occlusion according to operator volume.
