|LAA Morphology in 2D Imaging Reconstruction (CT/CMR)|
|Chicken Wing||Non–Chicken Wing||Sum|
|Evaluation in 3D TEE|
Assuming 2-dimensional (2D) imaging reconstruction by computed tomography (CT) or cardiac magnetic resonance (CMR) as the gold standard, 3-dimensional (3D) transesophageal echocardiography (TEE) shows 100% sensitivity and specificity in the differentiation between chicken wing and non–chicken wing morphology. Non–chicken wing morphology is considered to comprise those left atrial appendage (LAA) types with a higher rate of thromboembolic events.
