Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube is in good position at 5 .1 cm of the carina . However , the right subclavian line has been repositioned since the last exam . It is crossing the midline and its distal end is pointing downward on the left , which is unusual in a patient who does not have a left persistent superior vena cava . The exact location of the line can not be assessed with this exam . It could be in any structure , and it does not follow the course of the normal venous system . The distal end of the TNG is not included in this exam , but probably in a good position . Amelioration of the bilateral opacities compatible with mild edema . Deterioration of retrocardiac opacity compatible with atelectasis . Slight deterioration of the mild pleural effusions . No pneumothorax .
    OUTPUT:
