Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post median sternotomy and transcatheter aortic valve replacement . Moderate cardiomegaly is re - demonstrated with diffuse calcification of the thoracic aorta again noted . Mediastinal contour is stable with clips again demonstrated in the lower aspect of the neck likely related to prior thyroid surgery . Calcified bilateral pleural plaques are re - demonstrated which limit assessment of the underlying pulmonary parenchyma . There are likely streaky bibasilar airspace opacities , reflective of atelectasis . Small amount of right basal lateral pleural thickening versus fluid is noted . No pneumothorax is identified . No acute osseous abnormalities seen .
    OUTPUT:
    
Bilateral calcified pleural plaques compatible with prior asbestos exposure . These plaques limit assessment of the underlying pulmonary parenchyma , with streaky bibasilar airspace opacities likely reflective of atelectasis , but infection can not be excluded . Small right pleural effusion versus right basal lateral pleural thickening may be present .
