Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube is in appropriate position with the tip terminating 45 mm above the carina . A left - sided PICC line is unchanged in position with the tip projecting over the cavoatrial junction . A right internal jugular large - bore central catheter is unchanged in position with the tip terminating in the right atrium . An OG tube is in appropriate position . Bilateral pleural pigtail catheters are unchanged in position in the lower lobes . Increased opacification in the left lower lobe could be a combination of left - sided pleural effusion with associated atelectasis or in the appropriate clinical setting , focal consolidation . A small right - sided pleural effusion is stable with persistent opacity in the peripheral right lower lobe most likely atelectasis . The patient is status post median sternotomy with an atrial valve prosthesis consistent with Bentall procedure . The mediastinal contours are stable . The cardiac silhouette is severely enlarged with an apparent gradual increase in size from prior studies which is concerning for pericardial effusion .
    OUTPUT:
    
1 ) Increased opacification of the left lower lobe is most likely a small left - sided pleural effusion with associated atelectasis in this postoperative patient . 2 ) Stable small right - sided pleural effusion with associated atelectasis . 3 ) Increased size of enlarged cardiac silhouette over multiple priors and when compared to baseline raises the possibility of pericardial effusion . Findings were communicated by Dr . ___ to ___ of cardiac surgery by phone at 12 :55 pm on ___ .
