Review Case Reports
Commotio cordis. The single, most common cause of traumatic death in youth baseball.
Two cases of blunt chest trauma caused by a baseball are reported, including one death. At least one of these was in consequence of cardiac concussion or commotio cordis, an entity not described in teh pediatric literature. Concussion of the heart is a functional injury, in contrast to cardiac contusion or cardiac rupture, which pertains to structural injury. ⋯ There appears to be an increased pediatric susceptibility to this type of injury. Unfortunately, these cases are quite resistant to resuscitative therapy. Devices and techniques for primary and secondary prevention exist, but have yet to be systematically verified and implemented.
