Evaluating the radiographic assessment of pulmonary venous hypertension in chronic heart disease

Journal Article · · AJR, Am. J. Roentgenol.; (United States)
This study evaluated how accurately the chest film could be used to determine pulmonary capillary wedge pressure (PCW) in patients with chronic heart disease. Six experienced readers interpreted the erect posteroanterior chest radiographs of 50 patients whose measured PCWs ranged from 6 to 38 mm Hg. Direct numeric estimates of PCW from the films were closely related to measured levels of PCW. A combination of the judged degree of pulmonary blood flow redistribution (PFR) and three particular signs of pulmonary venous hypertension (PVH), basal and perihilar vascular blurring and alveolar edema, adequately summarized the radiographic information about PCW. These combined judgment of PFR/PVH identified films from patients with higher and lower PCW levels as accurately as readers' numeric estimates of PCW.
