[Traumatic tricuspid valve insufficiency].
We report a case of tricuspid insufficiency in connection with blunt chest trauma. The patient was involved in a car accident. The central venous catheter showed a right ventricular pressure curve, suggestive of a tricuspid valve insufficiency. A transoesophageal echocardiographic examination supported this by revealing a papillary muscle rupture. This kind of injury has been seen more frequently during the last 35 years, partly because of better diagnostic procedures and a better understanding of the pathology. The decelerating force in the right ventricular chamber produces a regurgitation thereby initiating rupture of the papillary muscle and/or the chordae tendinae. In a literature study twelve out of thirteen patients were involved in car accidents. Some of them had a dominant V-wave in the venous pulse curve, but no clinical observation is directly diagnostic. Therefore, cardiac lesions should be kept in mind whenever there is a history of blunt chest trauma. The best diagnostic approach is echocardiography.
