Left Ventricular Volume and Ejection Fraction: Validation of Real Time 3 Dimensional Transesophageal Echocardiography

NCT01734174 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2018-06-28

No results posted yet for this study

Summary

Echocardiography is an ultrasound-based imaging technique which can be performed through the esophagus (which lies behind the heart) and through the chest wall; both TEE and TTE are performed routinely as a monitoring and diagnostic tool at different times in the course of one cardiac surgery. The purpose of the study is to compare these two methods of echocardiography and comparing them to the 2D TEE and TTE assessments, which are routinely performed simultaneously. The study will also compare the echocardiography data to a third technique, thermodilution, which measures cardiac function via a pulmonary artery catheter.

Conditions

  • 3D Transesophageal and Transthoracic Echocardiogram

Interventions

PROCEDURE

transesophageal echocardiography (TEE)

Echocardiography is an ultrasound-based imaging technique which can be performed through the esophagus (which lies behind the heart) and is performed routinely as a monitoring and diagnostic tool at different times in the course of one cardiac surgery.

PROCEDURE

thermodilution

A catheter is positioned in the pulmonary artery and the heart function is assessed via thermodilution which involves measuring the temperature of blood when a known volume of fluid is injected through the catheter to determine how quickly blood is carried from one part of the catheter to the other.

PROCEDURE

transthoracic echocardiography (TTE)

Echocardiography is an ultrasound-based imaging technique which can be performed through the chest wall and is performed routinely as a monitoring and diagnostic tool at different times in the course of one cardiac surgery.
