Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A pacemaker / ICD device appears unchanged . A PICC line has been retracted and now terminates over the right brachiocephalic vein , probably at the point where it separates into subclavian and right internal jugular veins . There are patchy opacities at both lung bases most compatible with atelectasis , noting low lung volumes . Streaky right basilar atelectasis persists . Mild increased interstitial opacification and perihilar fullness suggest mild vascular congestion . There is no definite pleural effusion , although the left lateral lower chest is obscured by the pacemaker device , making one difficult to exclude .
    OUTPUT:
    
1 . Findings suggesting mild vascular congestion and bibasilar atelectasis . 2 . Interval retraction of right - sided PICC line , now terminating likely at the confluence of the right subclavian and internal jugular veins .
