Fig 2. 3D transesophageal echocardiography image showing the outpouching of the left atrial wall (arrow) close to the P3 scallop of the mitral valve. Abbreviations: LV, left ventricle; LA, left atrium). Fig 3. En face view of the mitral valve obtained with 3D transesophageal echocardiography. The left atrial appendage is seen at the 9 o’clock position, while an outpouching of the left atrial wall also is seen (4 o’clock) in close proximity to the P3 scallop of the posterior leaflet of the mitral valve (arrowhead). Abbreviations: AV, aortic valve; LAA, left atrial appendage.
