Résumé
Cardiac contusion is an increasingly recognized entity in patients with nonpenetrating chest injury. Unifortunately, the diagnosis of cardiac trauma, particularly cardiac contusion, is imprecise and may be confounded by the presence of associated injuries, hypoxia, shock, and metabolic abnormalities. Symptomatic cardiac injury follwing blunt chest trauma is relatively rare, and valvular injury is even rarer. The valves most commonly affected are mitral and tricuspid. Although tricuspid regurgitations are usually asymptomatic and can resolve spontaneously, recent developments in echocardiography made possible the precise diagnosis of valvular injuries noninvasively, The authors report the case of tricuspid regurgitation incidentally detected by echocardiography in a construction worker who had suffered multiple fractures.
