Clinical Trial Summary

This study aims to investigate whether the identification of acute myocardial dysfunction by 2D-strain transthoracic sonography in the first week following trauma would allow to better diagnose occult and severe patterns of myocardial contusion, in order to identify a subpopulation at higher risk of complications.

The measurement of myocardial strain (2D-strain) by transthoracic sonography is a robust tool to assess the myocardial function.

The investigators strongly suppose that the 2D-strain would allow to better identify subclinical MC in chest trauma, as well as the severe patterns that are associated with more organs dysfunctions and a worst outcome.

Description:

Thoracic trauma is the cause of significant morbidity and accounts for 25% of trauma-related deaths.

The myocardial contusion (MC) is a distinct injury, which has a prevalence increasing with the severity of the trauma. The diagnostic tool is a major factor to vary the prevalence of MC (i.e. clinical exam, biology, electrocardiogram), with the highest values for autopsy series, until 24% of patients. It does not exist therefore of gold standard for the diagnosis of MC in clinical practice leading to a modest knowledge of this nosological entity. In clinical practice, troponin plasma level determines the diagnostic.

Otherwise, the measurement of myocardial strain (2D-strain) by transthoracic echocardiography (TTE) is a robust tool to assess the myocardial function. This ultrasound analysis allows an objective and topographical quantification of an acute myocardial dysfunction, be it global or segmental. 2D-strain has been thus has been validated for the diagnosis of myocardial dysfunction in medical setting. Its use in trauma setting has never been reported.
