BackgroundThe risk of cardiac injury in blunt thoracic trauma is quite rare, occurring in only 0.1% of patients. The least common cardiac injury is coronary artery dissection. Most cardiac injuries result from high-energy mechanisms such as motor vehicle collisions. Even low-mechanism injuries that have been reported involved rapid deceleration.Case ReportWe present a case of traumatic coronary artery dissection that resulted from a low-energy blunt thoracic injury with no rapid deceleration. This patient had no other associated thoracic injuries, such as rib fractures or sternal fracture. Following presentation, our patient twice deteriorated into ventricular fibrillation and was successfully resuscitated each time. The coronary lesion was successfully stented and the patient was eventually discharged home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case underscores the importance of maintaining a high level of suspicion for coronary artery dissection even in low-energy mechanisms. An electrocardiogram should be obtained early, even in low-energy mechanisms. While patients with traumatic cardiac injuries will commonly present with other injuries, such as rib fractures, the absence of these injuries does not rule out cardiac injury.Copyright © 2019 Elsevier Inc.
