Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left - sided PICC line has been retracted somewhat and terminates in the mid portion of the superior vena cava . The heart is moderately enlarged , as before . There is a suggestion of upper zone re-distribution of pulmonary vascularity , which suggests pulmonary venous hypertension , but congestive heart failure has largely resolved . A developing opacity is suspected in the right lower lung , however , but not optimally evaluated with portable technique . Streaky left basilar opacity probably is probably compatible with minor atelectasis . There is no definite pleural effusion or pneumothorax .
    OUTPUT:
    
Near resolution of pulmonary edema . Possible developing opacity at the right lung base . Short - term followup radiographs with standard PA and lateral technique , if possible , may be helpful to assess for whether it may represent a focus of infection rather than atelectasis .
