Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided dual - lumen central venous catheter tip terminates in the right atrium , unchanged . Cardiac silhouette size remains moderately enlarged . The mediastinal contours similar . Multiple clips are again seen projecting over the left superior mediastinum . There is persistent mild pulmonary edema , slightly improved in the interval with small bilateral pleural effusions , likely slightly increased from the prior study . More focal patchy opacities at the lung bases may reflect atelectasis . No pneumothorax is detected . There are no acute osseous abnormalities .
    OUTPUT:
    
Mild pulmonary edema , perhaps minimally improved in the interval , with slightly increased small bilateral pleural effusions . More focal patchy opacities in the lung bases likely reflect areas of atelectasis .
