Standard biplane chest roentgenograms of 107 patients suffering from acquired mitral valve disease were independently interpreted by two radiologists. Fluoroscopy was performed for detection of mitral valve calcification. The effective pressures in the pulmonary vascular bed were not known at the time of the film reading. Using the most valuable roentgen signs (enlargement of the left atrium, valvular calcification, configuration of the right ventricular outflow tract, size of the central pulmonary arteries and degree of pulmonary interstitial edema), each case was graded from zero to nine points. The two readers widely agree in the classification of the roentgen findings in most cases. There is a strong positive correlation between the radiographic changes and the pulmonary artery mean pressure.
107例获得性二尖瓣疾病患者的标准双平面胸部X线片由两位放射科医生独立解读。进行荧光透视检查以检测二尖瓣钙化。在读片时，肺血管床的有效压力未知。利用最有价值的X线征象（左心房增大、瓣膜钙化、右心室流出道形态、中央肺动脉大小和肺间质水肿程度），对每个病例从0到9分进行分级。在大多数病例中，两位阅片者对X线表现的分类有广泛的共识。影像学改变与肺动脉平均压力之间存在强烈的正相关。
