Regional Differences in Color Tissue Doppler-Derived Measures of Longitudinal Right Ventricular Function Using Transesophageal and Transthoracic Echocardiography

Conclusions: In cardiac surgical patients under anesthesia, the IVA appears to be the most consistent variable in the evaluation of RV function measured by either the TTE (lateral wall) or TEE (inferior wall). Technical difficulties may preclude the use of the deformation parameters in the assessment of RV function.
