Validating Transesophageal Echocardiographic Measurements of Right Ventricular Function
Transesophageal echocardiography (TEE) is becoming a more prevalent method of monitoring and
diagnosis in the perioperative setting for critically ill patients and patients undergoing
cardiac surgery. Many TEE measurements are extrapolated from transthoracic echocardiography
(TTE) data and have not validated by transesophageal means. The aim of this study is to
validate TEE assessment of right ventricular function by comparing them to simultaneously
measured TTE measurements.
Likewise, there are currently no agreed upon values for RV free wall strain. Therefore, the
investigators will attempt to define a range of normal values of RV free wall strain as
compared to the other measures of RV function.

Traditionally, all echocardiographic measurements have been studied utilizing TTE. Therefore
the normal values and ranges for pathology findings have been defined by transthoracic means
alone. TEE offers different images planes when compared to TTE, which may make the
measurements obtained differ from those obtained by TTE. In the operating room environment
the vast majority of echocardiography is completed by transesophageal means for many reasons;
largely access to the patient and the continuous use of TEE as a hemodynamic monitor.
However, given the fact that most echocardiographic measurements have only been validated by
TTE, there remains a question as to the validity or precision of TEE-derived measurements.
