Traumatic tricuspid insufficiency, a rare complication of blunt chest trauma, has been reported with increasing frequency during the last 40 years. Automobile accidents are the leading cause of traumatic tricuspid valve regurgitation. The most frequently reported injury is chordal rupture, followed by rupture of the anterior papillary muscle and leaflet tear, primarily of the anterior leaflet. In the acute phase of the injury, the traumatic lesion may go undetected. In the chronic phase many patients remain asymptomatic and others exhibit symptoms and signs of moderate to severe right heart failure. Clinically overt right heart failure has been the traditional indication for surgery, which usually consisted of tricuspid valve replacement. More recently, a more aggressive strategy, with surgical repair of the valve performed before deterioration of the right ventricular function occurs, has been advocated.
