    INPUT: AP portable upright as well as a lateral view of the chest was provided . Midline sternotomy wires are again seen . The previously noted left IJ central venous catheter has been removed . Clips are noted in the right upper quadrant . The kyphotic angulation of the T - spine causes distortion of the chest on the frontal projection . However , allowing for this , there is no definite consolidation or pneumothorax . Blunting of the left CP angle is stable and could represent a small effusion . There is likely bibasilar atelectasis . No signs of pulmonary edema . Heart size is difficult to assess . Mediastinal contour is stable . Bony structures appear intact . No free air below the right hemidiaphragm .
    OUTPUT:
    
Stable , limited exam with small left effusion and probable bibasilar atelectasis .
