Blunt cardiac trauma: clinical manifestations and management.

In conclusion, blunt cardiac trauma is the leading cause of fatalities following motor vehicle accidents. Although many of the patients with anatomic cardiac injuries die at the scene, with improved prehospital care these patients have more likelihood of surviving the first hour and presenting to an emergency room alive for definitive treatment. Prompt recognition of the injury based on the mechanism and a high index of suspicion must lead to immediate surgical intervention in order for these patients to survive. Patients with functional cardiac injuries (myocardial contusion/concussion) usually present a much less urgent scenario. They should be triaged early on the basis of admission ECG and severity of pre-existing or associated injuries to appropriately monitored units. This will allow better allocation of scarce hospital resources rather than blindly pursuing "routine" (expensive) work-ups. The sequelae of these injuries are generally nonfatal. If serious sequelae do arise in the ICU or in the OR, prompt treatment with inotropic support is usually successful.
