Transesophageal Echocardiography To Diagnose Blunt Traumatic Aortic Injury Traumatic Aortic Injury

This is a multicentre prospective observational trial. All trauma patients with suspected BTAI at the emergency department (ED) will undergo resuscitative transesophageal echocardiography to evaluate the thoracic aorta. Resuscitative TEE is a minimally invasive procedure to evaluate all chest trauma patients. Besides the aorta, TEE can also provide other useful information regarding the hemodynamic status, cardiac function and lung pathology of the patient. Patients will be recruited into the study by investigators who take informed consent from the patient or next of kin prior to the TEE procedure. For all patients with suspected BTAI, CTA is mandatory to confirm the diagnosis of BTAI. TEE findings of BTAI will be compared to CTA which will be considered the reference standard unless confirmation is available from surgical procedures or autopsy. Inter-observer variability for normal or pathological TEE images interpretation is performed prior to the initiation of the study.
