    INPUT: Frontal AP and lateral views of the chest were obtained . Low lung volumes result in bronchovascular crowding . There are diffusely increased pulmonary markings with more focal opacity at the left base and right apex , which are new from ___ and may represent infection on a background of mild pulmonary edema . There are probably small pleural effusions . Cardiac and mediastinal silhouettes are stable allowing for lung volumes . The left pectoral pacemaker leads end in the right atrium and right ventricle . Median sternotomy wires are intact . A prosthetic aortic valve is again seen . A calcified granuloma is again seen in the right lower lung .
    OUTPUT:
    
Low lung volumes . Opacity in the left base and right apex may represent infection on a background of mild pulmonary edema . Recommend repeat radiograph after treatment , with improved inspiration , to document resolution .
