[A case of tricuspid annular calcification].
A 76-year-old man was referred to our hospital with complaints of productive cough, dyspnea and peripheral cyanosis. The chest X-ray film indicated the pulmonary emphysema and acute bronchitis, but no abnormal intracardiac calcification. The electrocardiogram revealed a peaked P-wave, complete left bundle branch block, and ventricular premature contraction. Chest tomography demonstrated abnormal intracardiac calcium deposition in the right heart region. Two-dimensional echocardiography revealed the tricuspid annular calcification in the postero-lateral portion, showing a synchronous movement with tricuspid annular motion throughout the cardiac cycle. The size of calcification was 10 x 14 mm. The tricuspid valve showed no significant regurgitation. Left ventricular dilatation, associated with mild mitral regurgitation and impairment of systolic function (EF = 49%) was revealed by echocardiography. Serum examination revealed positive in Wassermann reaction. This case of tricuspid annular calcification might be caused by atherosclerotic degenerative change related to the aging process, or by an unknown mechanism related to pulmonary emphysema.
