    INPUT: Right IJ central line tip overlies the right atrium common similar prior . Status post sternotomy . Mild prominence of cardiomediastinal silhouette overall similar to the prior study . As before , the right hilum is somewhat prominent . There is platelike atelectasis in both lower zones similar to prior , slightly more pronounced on the left . There is upper zone redistribution and mild diffuse vascular blurring , consistent with mild CHF . There is a new small to moderate left pleural effusion with increased retrocardiac density consistent with left lower lobe collapse and / or consolidation . Minimal blunting the right costophrenic angle and minimal atelectasis at the right lung base , without gross effusion . Advanced osteoarthritis of both glenohumeral joints again noted .
    OUTPUT:
    
Suspect slight interval increase in CHF . Increased opacity left base , consisting of increased left pleural effusion and increased retrocardiac density , compatible with left lower lobe collapse and / or consolidation . Minimal blunting of the right costophrenic angle , without gross right effusion . Minimal patchy atelectasis at the right lung base is similar to prior
