Figure 4 A comparison of ICE views with TEE views at four angles side by side in the assessment of device position before release in the same patient. ICE successfully displayed the long-axis views of the LAmbre device at 0°(A), 45°(B), 90°(C), 135°(D). TEE showed the long-axis views of the LAmbre device at 0°(E), 90°(G), 45°(H), but failed at the 135°(F) and showed the short-axis view of the device.
Supplementary movie 1 Significant residual flow was detected by ICE instead of TEE. TEE was able to display long-axis views of the device at 0°(A), 45°(B) and 90°(C) except 135°(D). No significant residual flow was detected by TEE. Significant residual flow was detected by ICE at 45° view using “FLAVOR” approach (E, F) immediately after TEE assessment (white arrows). Additional three-dimensional TEE (G) was used to confirm the residual flow in this patient, significant residual flow was visualized (white arrow).
