FINDINGS:
A dialysis catheter terminates in the right atrium.  There is a vascular stent
 projecting over the left chest apex which probably corresponds to a left
 subclavian venous stent.  The heart is again moderately enlarged.  The lung
 volumes are low.  There is no pleural effusion or pneumothorax.  The lungs
 appear clear.

IMPRESSION:
No evidence of acute disease.
