Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy , with mild prominence of the cardiomediastinal silhouette . The left ventricular silhouette itself appears smaller . Again seen is left - sided chest tube , similar in configuration . New compared with the prior study , there is much more extensive subcutaneous emphysema , now outlining the pectoralis muscle fibers and with prominent new subcutaneous emphysema in the left supraclavicular fossa . The left chest tube side port remains in a similar position , without obvious interval retraction . Lucency at the base of the left heart and along the left chest wall inferiorly is compatible with the known pneumothorax . The left apical component of the pneumothorax appears less pronounced , with only a small residual pneumothorax seen at the left lung apex . On the right , there is an equivocal small residual apical pneumothorax , decreased compare with the prior study . Upper zone redistribution , but no overt CHF . Atelectasis at the right base , which is more pronounced . No gross effusion on either side . Previously seen right IJ sheath is been removed . Small amounts of calcification are seen in both carotid arteries .
    OUTPUT:
    
1 . More extensive subcutaneous emphysema is seen on today 's study , including prominent subcutaneous emphysema in the left supraclavicular fossa . Left chest tube appears unchanged in configuration . Clinical correlation requested . 2 . Left apical pneumothorax is decreased in size , though residual left - sided pneumothorax is likely present at the left lung base . 3 . Equivocal minimal residual right apical pneumothorax . 4 . Overall cardiomediastinal silhouette is similar , though left ventricular silhouette appears subtly smaller . 5 . Upper zone redistribution and right base atelectasis . No overt CHF or frank right - sided consolidation .
