FINDINGS:
The lung volumes are stable.  A new right lower lung opacification. The cardio
 mediastinal and hilar borders are stable.  The pleural surfaces are stable. 
 The left pacemaker is intact with leads in appropriate positions.  Again seen,
 is destruction in the second sternotomy wire.  The OG tube appears to be
 malpositioned proximally lying in the proximal fundus of the stomach.  The
 right PICC line terminates in the mid SVC.  The osseous structures are stable.

IMPRESSION:
1. New right lower lung opacity may represent aspiration, less likely
 atelectasis.
 2.  Malpositioning of the OG tube.  Recommend advancement of the tube.
 
 RECOMMENDATION(S):  Advancement of the OG tube.
