title: [Radiographic examination of the thorax, fluoroscopy and echocardiography in cardiac calcification].
abstract: The value of radiographic examination of the thorax, fluoroscopy and echocardiography in demonstration and localization of intracardiac calcifications were compared in an investigation of 40 patients with valvular heart disease prior to planned cardiac catheterization or operation. Radiographic examination of the thorax revealed only the most severe calcifications. By means of echocardiography it proved possible to undertake a simple semi-quantitative characterisation of the calcified tissue with acceptable intra- and inter-observer variation. Echocardiography and fluoroscopy were found to be of equal value in demonstration of the degree of calcification of the heart. Echocardiography was, however, superior to fluoroscopy in fine localization of the calcifications. The relative and additive values of the methods could be illustrated employing Bayes' theorem and could be represented graphically provided that the observations carried out with the three methods could be considered independent of one another. It is concluded that radiographic examinations of the thorax is unsuitable for screening for cardiac calcifications. Fluoroscopy can no longer be considered to be the method of choice in assessing lesions of this type but should be employed in cases where echocardiography does not provide sufficient information or is not available. The greatest certainty in demonstration of calcifications is obtained with combined employment of fluoroscopy and echocardiography.
