Cardiac concussion, previously known as commotio cordis, occurs in structurally 
normal hearts without gross or microscopic injury to the myocardium, cardiac 
valves, or coronary arteries, as opposed to other sports-related deaths known to 
occur more frequently in structural or congenital heart disease. We describe the 
sudden cardiac death of a 2-year-old child, who died as a result of a blunt 
force impact to the chest. A thorough medicolegal investigation was necessary to 
determine that the child died as a result of foul play.
