    INPUT: Patient is status post median sternotomy and CABG . The cardiac silhouette remains enlarged but stable . There appears to be some pulmonary vascular congestion . Prominence of the right hilum is stable . Streaky left basilar opacity more likely relates to atelectasis than consolidation . No large pleural effusion , although there is slight blunting of the posterior right costophrenic angle on the lateral view and a trace pleural effusion is difficult to exclude . No pneumothorax .
    OUTPUT:
    
Again seen pulmonary vascular congestion and cardiomegaly .
