FINDINGS:
The heart is mildly enlarged.  There are streaky opacities in the
 bilateral bases, likely reflecting atelectasis.  The mediastinal contours are
 normal, with note made of calcification of the aortic knob.  The pulmonary
 vasculature is normal.  Clips are noted in the left apex.

IMPRESSION:
Bibasilar atelectasis and mild cardiomegaly, unchanged.
