    INPUT: An aortic stent graft begins along the arch of the aorta as before . The patient is status post sternotomy and replacement of both the mitral and tricuspid valves . The configuration of the cardiac , mediastinal and hilar contours is stable . A left - sided PICC line has been removed . There is a somewhat increased patchy opacification of the left lower lung , probably in the left lower lobe , including a small pleural effusion . Increasing multifocal opacities in the right lung suggest atelectasis or scarring . Findings suggest mild vascular asymmetry with interstitial prominence and peribronchial cuffing , somewhat more prominent on the right than the left . There is no pneumothorax .
    OUTPUT:
    
Findings suggesting mild vascular congestion . Slight increase in patchy left lower lobe opacification suggesting a small amount of pleural fluid and atelectasis .
