Cardiac damage in nonpenetrating chest injuries. Report of 5 cases.

: The Authors report 5 cases of cardiac injury after blunt chest trauma: (a) one right atrial disruption with acute tamponade treated successfully; (b) two left ventricular perforations with rib fractures: one patient was exsanguinated and died, the other one presented a late subacute cardiac tamponade with successful operative repair; (c) one isolated traumatic tricuspid insufficiency which was well tolerated; (d) one atrio-inferior caval disruption with acute tamponade. Cardiac damage secondary to nonpenetrating chest trauma is uncommon but with the present modes of high speed transportation they are occurring with increasing frequency; correct management of cardiac ruptures depends upon rapid recognition of the injury and expeditious surgical repair. The occurrence of tricuspid valvular lesions alone as a result of nonpenetrating trauma is not common. Echocardiographic examination after blunt chest trauma is a useful diagnosis procedure.
