CONCLUSION
3D TEE demonstrates utility in the placement and positioning of a single
femoral venous cannula across the IAS to provide drainage of both left
and right atria for initiation of LAVA-ECMO. This approach is feasible
in appropriate patients and may provide both adequate venous drainage as
well as indirect left ventricular venting. 3D TEE adds increased
confidence in the positioning of the distal and proximal ports required
for bi-atrial drainage.
