Three-dimensional transoesophageal echocardiography for cardiac output in critically ill patients: A pilot study of ultrasound versus the thermodilution method
Intérêt de l’échocardiographie trans-œsophagienne tridimensionnelle pour évaluer le débit cardiaque chez les patients admis en réanimation : étude pilote

Figure 1 : 

Post-processing of a three-dimensional transoesophageal echocardiography left ventricular (LV) dataset. The dedicated software semi-automatically determines LV end-diastolic volume (EDV), LV end-systolic volume (ESV) and LV ejection fraction (LVEF). Cardiac output (CO) was calculated as the product of LV stroke volume (SV) (EDVESV) multiplied by heart rate.
