Color Doppler TEE midesophageal short-axis view. (A) Color Doppler TEE in the supine position showed red-colored blood flow from the IVC directed toward the IAS (white arrows) and blue-colored blood flow passing through the ASD from the LA to the RA, indicating a left-to-right shunt (yellow arrowheads and Video 5). (B) Color Doppler TEE in the upright sitting position showed that the IAS bulged significantly into the LA (white arrowheads) and the ASD and blood flow from the IVC (white arrows) were aligned, which directed blood flow from the IVC toward and through the ASD (yellow arrowheads), indicating a right-to-left shunt (Video 6).
