[Heart contusion as an unusual cause of shock in severe polytrauma].

The reported incidence of myocardial contusion after blunt chest trauma is 7-17%. Only one third of these patients present with significant morbidity. The polytrauma is generally dominated by hypovolemic and traumatic shock. Other causes of hypotension are less common, and may thus be ignored. The standard algorithm of care in multiple trauma care, however, leads to the diagnosis even in these cases, as illustrated by a case of prolonged shock induced by blunt myocardial trauma.
