    INPUT: Portable radiograph of the chest demonstrates median sternotomy wires as well as prosthetic aortic valve , in appropriate position . The heart size appears mildly enlarged , and there is bilateral perihilar haziness as well as increased prominence of the interstitial markings within the bilateral lungs , consistent with pulmonary edema . There are bilateral pleural effusions , left greater than right , which obscures the left heart border , and underlying infection can not be completely excluded , however no focal pneumonia is identified . Bibasilar atelectasis is present . Surgical clips are present in the upper mid abdomen as well as over the right chest wall , presumably from prior mastectomy .
    OUTPUT:
    
Pulmonary edema with bilateral pleural effusions and bibasilar atelectasis . Although no focal pneumonia is seen , an underlying infectious process can not be completely excluded .
