Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post median sternotomy , CABG , and stenting of a bypass graft . Severe cardiac enlargement is relatively similar compared to the previous exam allowing for differences in technique . The aorta remains tortuous with atherosclerotic calcifications noted at the aortic arch . Bilateral perihilar haziness with vascular indistinctness and bibasilar opacities likely reflect mild to moderate pulmonary edema with small bilateral pleural effusions , greater on the left . There is also likely bibasilar atelectasis , but infection can not be completely excluded . Mild elevation of the right hemidiaphragm is unchanged . There is no pneumothorax . Extensive vascular calcifications are present within the upper abdomen , and multiple calcifications are seen projecting within the left upper quadrant of the abdomen compatible with splenic granulomas . Remote bilateral rib fractures are re - demonstrated .
    OUTPUT:
    
Mild to moderate pulmonary edema with small bilateral pleural effusions . Bibasilar airspace opacities could reflect atelectasis but infection is difficult to exclude .
