Figure 1
Congenital LAA absence. (A, B) Multiplanar reconstruction axial image from CCTA demonstrates nonvisualization of the LAA adjacent to the left superior pulmonary vein (LSPV). (C) Three-dimensional TEE shows the surgeon's view and congenital absence of the LAA. (D) Transesophageal echocardiographic view at 60° confirms congenital absence of the LAA. AO, Aorta; AV, aortic valve; LA, left atrium; LV, left ventricle; MV, mitral valve.

Figure 2
Diminutive LAA. (A) A small LAA sliver with minimal blood flow is seen on TEE in the 60° view. (B) Pulsed-wave Doppler evaluation shows low-velocity blood flow. (C) Definity contrast image shows minimal late filling of contrast in the LAA sliver. (D) The LAA orifice is seen on three-dimensional TEE. (E) CCTA shows a rudimentary appendage that did not opacify with contrast. AO, Aorta; AV, aortic valve; DA, descending aorta; LA, left atrium; LSPV, left superior pulmonary vein; LV, left ventricle; MV, mitral valve; PA, pulmonary artery; RA, right atrium.
