FINDINGS:
Patient is status post median sternotomy and coronary artery bypass
 surgery.  ICD remains in place as well as a right PICC.  Cardiac silhouette is
 mildly enlarged, and accompanied by mild pulmonary vascular congestion. 
 Persistent patchy right basilar opacity and new patchy left lower lobe opacity
 as well as a persistent linear area of atelectasis in the left lower lobe. 
 The etiology of the basilar opacities is uncertain, but could represent
 aspiration, infectious pneumonia, or a dependent distribution of edema in the
 setting of known upper lobe predominant emphysema.
