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.
在50例单纯风湿性二尖瓣狭窄（MS）患者中，比较了二维超声心动图与计算机断层扫描（CT）在评估二尖瓣钙化方面的效果。超声心动图显示，23例患者无二尖瓣钙化，占比46%（0级）。12例患者（24%）有小于2.5毫米的钙化（1级）。11例（22%）有中度钙化，小于二尖瓣前叶长度的一半（2级），4例（8%）有大于二尖瓣前叶长度一半的钙化（3级）。后两组被认为有临床上重要的钙化。与CT相比，检测了特异性和敏感性。通过超声心动图，在2级组中发现5例（10%）假阳性结果。后两组既无假阳性也无假阴性结果。第一组与其他三组相比，敏感性为100%，特异性为85%，预测准确性为81%。但前两组与后两组相比，敏感性、特异性和预测准确性均为100%。
