Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderate to severe enlargement of cardiac silhouette is re - demonstrated . The mediastinal contours are stable , with atherosclerotic calcification of the thoracic aorta noted . The hilar contours remain enlarged , with perihilar haziness and vascular indistinctness compatible with mild pulmonary edema , findings which appear slightly progressed when compared to the radiograph obtained earlier the same day . More focal opacity within the peripheral aspect of the left lung base appears more pronounced compared to the prior exam , and infection or aspiration is not excluded . No large pleural effusion or pneumothorax is identified . There is no free subdiaphragmatic air . Multiple clips are seen along the left lateral chest wall .
    OUTPUT:
    
Mild pulmonary edema , progressed when compared to the radiograph obtained earlier the same day . More focal opacity within the periphery of the left lung base also appears more pronounced than on the prior study , and is non-specific , but could reflect an area of infection or aspiration . Follow up radiographs after diuresis are recommended .
