2 × 2 Contingency Table: Comparison of 3D TEE and 2D Imaging Reconstruction (CT/CMR)
| LAA Morphology in 2D Imaging Reconstruction (CT/CMR) | |||
|---|---|---|---|
| Chicken Wing | Non–Chicken Wing | Sum | |
| Evaluation in 3D TEE | |||
| Chicken wing | 21 | 0 | 21 |
| Non–chicken wing | 0 | 45 | 45 |
| Sum | 21 | 45 | — |
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.
