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.
