FINDINGS:
The patient is status post median sternotomy and CABG.  The heart is mild to
 moderately enlarged, unchanged.  Mediastinal and hilar contours are unchanged.
 Mild pulmonary vascular engorgement is present, not significantly changed
 compared to the prior radiograph.  No pleural effusion or pneumothorax is
 seen.  Bibasilar airspace opacities are likely reflective of atelectasis.
