    INPUT: The lungs are well expanded with diffuse bilateral heterogeneous interstitial and alveolar opacities . A moderate - sized left pleural effusion with left lower lobe atelectasis is seen . The right pleural surface is normal . No pneumothorax . The heart is partially obscured by pleural effusion ; however , is enlarged with mediastinal vein dilatation . Mediastinal contour is otherwise unremarkable and there is prominence of the hilum bilaterally . Sternotomy wires are unchanged in position and are intact . Right axillary clips , mitral annulus calcification , and valvular replacement are again noted .
    OUTPUT:
    
1 . Moderate pulmonary edema with increased moderate left pleural effusion . 2 . Left lower lobe opacity likely represents left pleural effusion and atelectasis ; however , underlying consolidation is difficult to exclude .
