Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Re-identified is a right IJ central venous catheter with tip projecting over the high right atrium versus cavoatrial junction . Also unchanged are multiple median sternotomy wires and mediastinal surgical clips . There are very low lung volumes , likely accentuating the size of the cardiomediastinal silhouette , stable in size from prior exam . The hila are not well assessed on this exam . Retrocardiac opacity is persistent , with increased hazy opacification of most of the left lower lung , probably representing a combination of layering pleural fluid and atelectasis . Left pleural fusion is likely mildly larger in comparison to prior exam , now all small to moderate . Right moderate pleural effusion is also likely slightly larger , tracking along the right pleural space , with unchanged right basilar atelectasis . There is no new superimposed focal lung consolidation . There is no pulmonary edema . There is no pneumothorax .
    OUTPUT:
    
Very low lung volumes . Mildly increased bilateral small to moderate pleural effusions with adjacent bibasilar atelectasis . No edema or definite new focal lung consolidation .
