Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Sternotomy wires are intact . Right pectoral infusion port terminates at the cavoatrial junction . Prosthetic aortic valve and TAVR is in unchanged position . Lung volume is low . Chronic interstitial fibrosis is similar to before . Focal areas of increased opacity in the periphery of the right mid and left lower lungs appear more conspicuous than on the prior radiograph , but lower lung volumes limit comparison . There is no pleural effusion or pneumothorax . Cardiac silhouette is normal size .
    OUTPUT:
    
1 . Increased constant acuity of right mid and left lower lung opacities , possibly due to accentuation by lower lung volumes . Followup PA and lateral radiographs would be helpful for more complete assessment when the patient 's condition allows , in order to exclude developing pneumonia at either of the sites . . 2 . Extensive interstitial fibrosis .
