    INPUT: Since prior chest radiograph performed earlier on the same date , there has been interval placement of a right subclavian line which terminates in the low SVC . Endotracheal tube and enteric tubes are otherwise unremarkable in appearance . Lung volumes remain low , with crowding of bronchovascular structures . Left retrocardiac opacity likely represents atelectasis , although infection or aspiration could be considered in the appropriate clinical setting . No pleural effusion or pneumothorax . Heart size is likely normal , accounting for portable technique .
    OUTPUT:
    
New right subclavian line terminates in the low SVC . Otherwise no relevant change .
