Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There again surgical clips in the mediastinum . The heart appears mildly enlarged . There is increased prominence in the aortopulmonary window which is suggestive of enlarged left atrial appendage . On the right there is probably a trace pleural effusion . On the left , there is a small to moderate pleural effusion with associated opacity probably due to atelectasis in the posterior left lower lobe . More generally , a moderate interstitial abnormality is most suggestive of congestive heart failure . Fissures are thickened . The right hilum appears more prominent than before and in addition there is the possibility of developing focal opacity at the right lung base . Streaky opacities in the lingula appear unchanged suggesting background scarring and mild volume loss , as depicted on prior studies .
    OUTPUT:
    
1 . Findings consistent with moderate congestive heart failure including pleural effusions with suspected left basilar atelectasis . Pneumonia is not excluded , however . 2 . Possible developing opacity at the right lung base versus regional edema . In addition to that , right hilum appears enlarged . Although these findings may be congestive in nature , re-evaluation in follow - up radiographs is recommended after treatment .
