The Left Atrial Appendage Revised

Brazilian Journal of Cardiovascular Surgery, 2017
Nonvalvular atrial fibrillation is associated with a 4- to 5-fold strokes increase and may be responsible for 15% to 20% of all strokes in the elderly. In this scenario, the left atrial appendage thrombus would be the associated with 90% of cases.

Left Atrial Appendage Occlusion for Stroke Prevention in Nonvalvular Atrial Fibrillation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
The majority of embolic strokes in patients with nonvalvular atrial fibrillation are caused by thrombi in the left atrial appendage. It is projected that strokes related to atrial fibrillation will markedly increase in the future unless effective ...

A Misleading Left Atrial Appendage

JACC: Case Reports, 2023
Left atrial appendage collapse is a relatively unusual echocardiographic finding. Although in post-cardiac surgery patients it may be an early sign of cardiac tamponade, and pericardiocentesis should be discussed, a conservative approach may be followed in cases secondary to viral infection without confusing it with a left atrial appendage thrombus ...

Left Atrial Appendage Remodeling After Lariat Left Atrial Appendage Ligation [PDF]

Circulation: Arrhythmia and Electrophysiology, 2015
Background— Left atrial appendage (LAA) ligation with the Lariat device is being used for stroke prevention in atrial fibrillation. Residual leaks into the LAA are commonly reported after the procedure. Little is known about the anatomic LAA remodeling after Lariat ligation. Methods and Results—

Left Atrial Appendage Closure: A Current Overview Focused on Technical Aspects and Different Approaches

Reviews in Cardiovascular Medicine, 2022
Several studies in literature have shown that 90% of emboli related to non-valvular atrial fibrillation originate from left atrial appendage. Percutaneous closure or surgical exclusion of left atrial appendage in patients with high bleeding and high ...

The missing left atrial appendage [PDF]

Journal of Cardiovascular Computed Tomography, 2012
A 34 year old man underwent a transesophageal echocardiogram (TEE) prior to implantation of a biventricular ICD and DC cardioversion, to exclude left atrium and left atrial appendage thrombus. He had a history of repaired tetralogy of Fallot as a child, Stickler syndrome, atrial flutter and was status post recent mitral valve replacement, pulmonary ...

Aneurysm of the left atrial appendage [PDF]

Clinical Cardiology, 1979
AbstractA 2‐year old asymptomatic girl is presented in whom the chest x‐ray film led to the discovery of a grossly distorted cardiac shadow. Angiocardiography showed a giant aneurysm originating from the left atrium. At operation an intrapericardial aneurysm of the left atrial appendage, measuring 12 × 4 × 4 cm, was found. It communicated with the left
