FINDINGS:
Mild enlargement of the cardiac silhouette is similar.  The aorta is tortuous.
 Patient is status post TAVR, in unchanged position.  Diffuse increased
 interstitial opacities are re- demonstrated suggestive of chronic interstitial
 lung disease.  More focal opacities within the lung bases likely reflect areas
 of atelectasis.  No pleural effusion or pneumothorax is present. No definite
 pulmonary edema is identified.  Partially imaged is lumbar spine fusion
 hardware.

IMPRESSION:
Bibasilar patchy atelectasis superimposed upon a background of chronic
 interstitial lung disease.
