Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post coronary artery bypass graft surgery . There is persistent leftward shift of mediastinal structures , possibly with some volume loss in the left lung and similar patchy mid lung opacification . A calcified pleural plaque is also noted in the left hemithorax . Widespread opacification of the right mid-to - lower lung is new including interstitial changes including Kerley B lines identifiable at the right lung base . Small pleural effusions are difficult to exclude . Rightward convex spinal curvature is similar .
    OUTPUT:
    
Findings suggesting moderate pulmonary edema . If that interpretation is compatible with clinical findings then repeat radiographs are suggested after treatment in order to assess whether an additional pulmonary process such as aspiration or pneumonia may potentially coincide .
