FINDINGS:
The patient is status post median sternotomy, CABG, and mitral valve
 replacement. Heart size remains mildly enlarged, stable. The mediastinal and
 hilar contours are unchanged. Atherosclerotic calcifications are noted at the
 aortic knob. The pulmonary vasculature is normal. Linear opacities in the left
 lower lobe likely reflect subsegmental atelectasis. Left lateral basilar
 pleural thickening is unchanged. No new focal consolidation, pleural effusion
 or pneumothorax is present. No acute osseous abnormalities demonstrated.

IMPRESSION:
No acute cardiopulmonary abnormality.
