Patients with traumatic cardiac injuries can present with wide variability in their severity of illness. The most severe will present in cardiac arrest, whereas the most benign may be altogether asymptomatic; most will fall somewhere in between. Management of cardiac injuries largely depends on mechanism of injury and patient physiology. Understanding the spectrum of injuries and their associated manifestations can help providers react more quickly and initiate potentially life-saving therapies more efficiently when time is critical. This article discusses the workup and management of both blunt and penetrating cardiac injuries.
