Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to the chest radiograph obtained 1 day prior , pulmonary edema has worsened . There are increased opacities most prominently in the right upper lung and left lower lung , possibly a combination of asymmetric and dependent edema due to mitral regurgitation and volume overload , developing pneumonia , or atelectasis . Moderate cardiomegaly is unchanged . Pleural effusions small , if any . Tracheal stenosis may reflect complications of prior intubation or tracheostomy . The intra-aortic balloon pump is unchanged in position , but approximately 3 cm superior to standard placement . The Swan - Ganz central venous catheter is unchanged in position and terminates in the mid right descending pulmonary artery .
    OUTPUT:
    
Increased , moderate pulmonary edema . An asymmetric , right upper lobe predominance may reflect mitral regurgitation . Alternatively , there may be a developing right upper lobe and / or a left lower lobe pneumonia . Intra-aortic balloon pump unchanged in position , but 3 cm superior to standard placement .
