Chest films, right sided heart catheterization, and measurement of the regional lung perfusion, using 133Xe, were carried out 31 times on patients with mitral valve disease. A relationship was found between the radiologic evaluation in 3 grades, and the values of pulmonary wedge pressure and the apical and basal perfusion. Changes in flow distribution as reflected in altered appearance of the vessels and the presence of interstitial edema were found to be the most sensitive factors in the evaluation of pulmonary wedge pressure. Chest radiography was thus found suitable for the evaluation of pulmonary wedge pressure in mitral valve disease.
对二尖瓣疾病患者进行了31次胸部X光检查、右侧心导管插入术以及使用氙-133测量局部肺灌注。发现3级放射学评估与肺楔压值以及尖部和基部灌注之间存在关联。血管外观改变和间质性水肿所反映的血流分布变化被发现是评估肺楔压时最敏感的因素。因此，胸部X光检查被认为适用于评估二尖瓣疾病中的肺楔压。
