Figure 1: Three-dimensional heart model shown in cross-section to highlight the position of the TEE plane in the mid esophageal right ventricular inflow-outflow view. A) Anterior view of the heart with TEE plane. B) Right lateral view of the heart and TEE plane. The blue dotted line represents the orientation of the pulsed wave cursor and the blue circle indicates the position of the sample box at the tip of the tricuspid valve leaflets. Key: ATVL = Anterior/Septal Tricuspid Valve Leaflet, AV = Aortic Valve, LA = Left Atrium, PTVL = Posterior Tricuspid Valve Leaflet, PV = Pulmonic Valve, PA = Pulmonary Artery, RA = Right Atrium, RVOT = Right Ventricle Outflow Tract.

Figure 2: Spectral doppler data acquired for blood flow through the tricuspid valve. In the upper right, a two dimensional TEE image of the mid-esophageal right ventricular outflow view; the blue circle indicates the location of the sample volume at the tip of the tricuspid valve leaflets. In the lower half of the image, a spectral doppler trace shows the relationship between blood velocity and time. The baseline is orange. Key: E = Early diastolic filling wave, A = Atrial kick wave.
