Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is mildly enlarged but similar . The aorta is tortuous . Mediastinal and hilar contours are unchanged . The pulmonary vasculature is not engorged . Streaky opacities within the lung bases likely reflect areas of atelectasis . Minimal blunting of the costophrenic angle posteriorly on the right may suggest the presence of a small right pleural effusion . Multiple clips are again noted within the right aspect of the anterior mediastinum with prior mitral valve repair . No pneumothorax is identified . No acute osseous abnormality is detected .
    OUTPUT:
    
Streaky bibasilar opacities , likely atelectasis , with probable trace right pleural effusion .
