Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The Swan - Ganz catheter has been removed . The nasogastric tube extends into the stomach , distal tip not visualized . A right - sided PICC line extends into the low right atrium . Retraction by 7 - 8 cm would position its tip in the low SVC . There is no pneumothorax . Retrocardiac airspace opacification has decreased , likely due to resolved atelectasis . The lungs are otherwise clear . Heart size is smaller , but magnified by the projection . A moderate hiatal hernia is unchanged .
    OUTPUT:
    
Right - sided PICC line terminates in the right atrium . Retraction by 7 - 8 cm would reposition the tip in the low SVC . Resolved left basilar subsegmental atelectasis . Moderate hiatal hernia .
