    INPUT: The heart remains moderately enlarged . The aorta is tortuous and calcified . Mediastinal and hilar contours are otherwise unchanged . No pulmonary edema is identified . Small bilateral pleural effusions , left greater than right are re- demonstrated . Bibasilar airspace opacities likely reflect compressive atelectasis though infection can not be completely excluded . There is no pneumothorax . No acute osseous abnormalities are identified . Multiple clips are again seen within the left hemiabdomen .
    OUTPUT:
    
Small bilateral pleural effusions , left greater than right , likely similar in extent compared to the prior study allowing for differences in positioning . Associated bibasilar atelectasis . No evidence for widened mediastinum .
