FINDINGS:
Position of endotracheal tube and right-sided Swan-Ganz is
 unchanged.  NG tube projects over the stomach.  Sternotomy wires and outline
 of artificial mitral valve noted.  Heart is moderately enlarged as before. 
 Mild bilateral pleural effusions are unchanged.  Bilateral patchy lung
 opacifications, likely represent atelectasis and crowding of pulmonary
 vasculature secondary to low volumes.  No focal areas of consolidation to
 suggest pneumonia.  No pneumothorax.

IMPRESSION:
No significant changes compared to the prior study.
