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

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

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.
