Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable view of the chest was reviewed . Again seen are median sternotomy wires as well as a prosthetic aortic valve , in standard positions . Significant mitral annular calcifications are again noted . There is mild cardiomegaly , stable over the past 10 days . A left pleural effusion with underlying atelectasis obscures the left heart border . There is no pneumothorax . Mild pulmonary edema is seen . Slightly increased and more confluent interstitial markings in the right lateral mid lung may be indicative of an infectious process . Alternatively , mitral regurgitation may result in asymmetric right upper lobe pulmonary edema from aberrant blood flow into the right superior pulmonary vein .
    OUTPUT:
    
Bilateral pleural effusions with pulmonary edema . More confluent consolidation in the right mid lung may represent a developing pneumonia or asymmetric pulmonary edema related to mitral regurgitation .
