Conclusion
The novel use of the TEE probe for transthoracic examination of patients
in the prone position is feasible and reproducible. There was a good
agreement between the 2D linear measurements of the LV and AoR in the
prone position compared to the corresponding measurements obtained in
the supine position by the standard transthoracic technique. However,
the EF was lower, and left atrial anteroposterior diameter was smaller
in the prone position.
