Transesophageal echocardiography midesophageal short-axis view. (A) In the supine position, TEE showed a small ASD and the IAS did not bulge significantly into the LA (white arrowheads). The size of the ASD was 4.5 mm (Video 3). (B) In the upright sitting position, TEE showed that the IAS bulged significantly into the LA (white arrowheads). The size of the ASD was 4.6 mm and was not significantly larger than in the supine position; therefore stretch of the ASD was not obvious. In this case, there was no venous valve remnant such as a Eustachian valve (Video 4).
