Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right IJ central line tip overlies the proximal SVC . No pneumothorax is detected . Again seen is hyperinflation suggesting background COPD . Moderate cardiomegaly , with mediastinal widening , are similar to the prior film . Again noted is radiodensity consistent with trans aortic valve replacement ( TAVR ) . There is mild pulmonary vascular congestion which is similar , possibly very slightly improved . This is probably superimposed on background parenchymal scarring . Blunting of right - greater - than - left costophrenic angles is consistent with a small amount of pleural fluid or thickening . Elevated right hemidiaphragm is again noted . Atelectasis at the right base is slightly more pronounced and atelectasis at the left base is slightly improved . No frank consolidation is identified .
    OUTPUT:
    
Minimal , if any , interval change compared with ___ at 07 : 57 , detailed above .
