title: Tricuspid regurgitation due to blunt chest trauma. Report of a case and review of the literature.
abstract: A 25-year-old female developed high-grade atrioventricular block and markedly elevated central venous pressure after sustaining a crushing injury to the chest while driving a car. An echocardiographic examination with color Doppler revealed severe tricuspid regurgitation due to a torn papillary muscle. An extensive review of the literature showed the following: 1) correct diagnosis is often delayed because of coexisting multisystem involvement and the subtleness of abnormal physical signs, 2) identification of abnormally elevated right atrial pressure with a prominent "v" wave, and characteristic electrocardiogram appeared to be the key to early diagnosis, and 3) the final diagnosis may be confirmed by echocardiography with Doppler and/or cardiac catheterization. The role of echocardiographic examination with color Doppler technique deserves special emphasis because the final diagnosis can be easily reached during the acute phase at the bedside noninvasively.
