Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with ___ allowing for differences in technique , no definite change detected . Slight blurring may relate to motion . The cardiomediastinal silhouette is similar , allowing for slight patient rotation . The transcatheter aortic valve replacement is again noted , similar in configuration . There is mild upper zone redistribution . Previously seen mild diffuse increased interstitial markings less apparent , likely due to motion - related blurring . No frank consolidation or gross effusion is identified . No pneumothorax detected . Previous studies have demonstrated a hiatal hernia . This likely accounts for the rounded area of lucency and density superimposed over the left cardiac silhouette on this study .
    OUTPUT:
    
1 . No focal consolidation or gross effusion . Minimal bibasilar atelectasis may be present . 2 . Upper zone redistribution . 3 . Previously seen increased interstitial markings are less apparent . I suspect this may be due to slight blurring from motion .
