BackgroundFew studies of pediatric cardiac injuries have been conducted in large cohorts. We, therefore, investigated the epidemiology of these injuries in the United States.MethodsWe identified patients with traumatic cardiac injury from the National Trauma Data Bank, using the International Classification of Diseases, Ninth Revision, codes. Demographic data, clinical data, and inhospital outcomes were compared among 5 age groups. A logistic regression model was used to determine adjusted mortality among these groups.ResultsSix hundred twenty-six patients met criteria. Fifty-nine percent sustained cardiac contusion; 36%, laceration. Penetrating injuries proved more severe than blunt, having lower average Glasgow Coma Scale (6.8 vs 8.7) and higher percentage of patients with Glasgow Coma Scale of 8 or lower (68% vs 53%). Associated injuries occurred in 484 (77%), most common being lung injuries (46%), hemopneumothorax (37%), and rib fractures (26%). Eleven percent underwent laparotomy; 9%, thoracotomy; 2%, craniotomy/craniectomy; and 0.2%, sternotomy. Complications occurred in 80 (13%), most common being cardiac arrest (4%). Firearm injuries result in the highest mortality rate (76%), compared with other mechanisms (26%-31%). Crude mortality in different age strata showed significant differences that were lost after adjustment for confounding variables.ConclusionsThe predominant cardiac injury was blunt (65%; 35% sustained penetrating insults), frequently paired with contusion. Pediatric cardiac injury is associated with excessive inhospital mortality (40%), with no age-related difference in adjusted mortality.Copyright © 2011 Elsevier Inc. All rights reserved.
