[A case of long-standing isolated traumatic tricuspid regurgitation with remarkably dilated right cardiac chambers and pancytopenia].
We report a rare case of tricuspid regurgitation due to nonpenetrating chest trauma 33 years previously. A 79-year-old man suffered a blunt trauma due to a piece of wood at work in 1958. He suffered multiple rib fractures on the right side and was admitted. Since then, he began having shortness of breath on exertion and was treated with medication. The patient was transferred to the Division of Cardiology, Hakodate National Hospital in 1984. A chest x-ray film revealed a marked cardiomegaly. Cardiac catheterization showed severe tricuspid regurgitation. Hepatomegaly and pancytopenia was observed. He was readmitted because of general fatigue in July 1991. Two-dimensional echocardiography demonstrated systolic excursion of septal and posterior tricuspid leaflets with ruptured chordae tendineae into the right atrium, and a remarkably enlarged right ventricule, right atrium and vena cava interior. Cardiac catheterization was performed. The right atrial pressure-wave form resembled the right ventricular pressure recording (ventricularization of the atrial pressure). Right ventricular cineangiography revealed severe tricuspid regurgitation, grade 4. Laboratory data showed pancytopenia. Thrombocytopenia progressed (3 x 10(4)/mm3), and a hemorrhagic tendency developed. The liver edge was palpable 4 finger breadths below the right costal margin. Pancytopenia due to congestive hepatomegaly and hypersplenism would have complicated this case.
