Imaging patients with cardiac trauma

Area of Science:

• Emergency Medicine
• Radiology
• Cardiology

Background:

• Trauma is a leading cause of death in the US, particularly among young adults.
• Cardiovascular injuries are the second leading cause of traumatic death, following central nervous system injuries.
• Evaluating suspected cardiac injury in trauma patients can be complex, involving various diagnostic methods.

Purpose of the Study:

• To highlight the utility of contrast material-enhanced computed tomography (CT) in evaluating hemodynamically stable trauma patients with suspected cardiac injury.
• To discuss the significance of findings such as hemopericardium, cardiac tamponade, pericardial rupture, and cardiac herniation.
• To emphasize the complementary roles of clinical and imaging findings in diagnosing cardiac injuries, especially in time-critical situations.

Main Methods:

• Contrast material-enhanced computed tomography (CT) is presented as a key imaging modality.
• Discussion includes the detection of hemopericardium, cardiac tamponade, pericardial rupture, and cardiac herniation.
• Other imaging modalities like chest radiography, echocardiography, nuclear medicine, and MRI are mentioned for selected cases.

Main Results:

• Contrast-enhanced CT is highly valuable for diagnosing cardiac injuries in hemodynamically stable patients.
• Significant findings like hemopericardium and cardiac tamponade are readily depicted.
• Multidetector CT can effectively visualize complications such as pericardial rupture and cardiac herniation.

Conclusions:

• Contrast-enhanced CT is a crucial tool for assessing cardiac injuries in stable trauma patients.
• Timely imaging is beneficial, particularly for penetrating cardiac injuries.
• A combination of clinical assessment and imaging findings is essential for accurate diagnosis and management.
