[Significance of two-dimensional echocardiography in the diagnosis of mitral valve calcification--sensitivity and specificity].
The effect of two-dimensional echocardiography in assessment mitral valve calcifications was compared to computed tomography (CT) in 50 patients with pure rheumatic mitral stenosis (MS). Echocardiography revealed no mitral calcifications in 23 patients, respectively 46 per cent (grade 0). Twelve patients (24 per cent) had calcifications smaller than 2.5 mm (grade 1). Eleven (22 per cent) had moderate calcifications, smaller than one half of length of the anterior mitral leaflet (grade 2) and four (8 per cent) had calcifications larger than one half of the length of the anterior mitral leaflet (grade 3). The last two groups were thought to have clinically important calcifications. Specificity and sensitivity were examined in comparison to CT. By echocardiography, five (ten per cent) false positive findings were found in the group 2. There were neither false positive nor false negative findings in the last two group. The first group when compared with other three groups showed sensitivity of 100, specificity of 85, and predictive accuracy of 81 per cent. But the first two groups together compared with the last two groups showed sensitivity, specificity and predictive accuracy of 100 per cent.
