This case report describes the disparity between the findings of the plain chest film and the echocardiogram in a patient with severe coronary artery disease. Whereas the plain chest film shows a normal cardiothoracic ratio of 50% indicating normal LV size, the echocardiogram shows features characteristic of a dilated cardiomyopathic left ventricle with low amplitude of wall motion and consequently low ejection fractoin. These echocardiographic findings were confirmed at cardiac catheterization and angiography. We propose the use of echo instead of the plain chest film in the evaluation of LV size in the cardiac patient.
本病例报告描述了一名严重冠状动脉疾病患者的胸部平片与超声心动图检查结果之间的差异。胸部平片显示心胸比为50%，属正常，提示左心室大小正常；而超声心动图显示为扩张型心肌病的左心室特征，室壁运动幅度低，因此射血分数也低。这些超声心动图检查结果在心脏导管插入术和血管造影术中得到了证实。我们建议在评估心脏病患者的左心室大小时使用超声心动图而非胸部平片。
