Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post median sternotomy CABG . Right - sided dual chamber pacemaker is noted with leads terminating in the right atrium and right ventricle , unchanged . There is mild to moderate cardiomegaly which is stable . The aorta is mildly tortuous and diffusely calcified . Small bilateral pleural effusions are noted with fluid identified within the fissures . Smoothly lobulated opacity overlying the right apex is compatible with a loculated pleural effusion which has slightly increased when compared to the prior study . Ill - defined streaky opacity within the right lung base appears slightly worsened in the interval , which could reflect asymmetric pulmonary edema though infection in the right lung base is not completely excluded . The left lung is grossly clear . There is diffuse demineralization of the osseous structures with compression deformities in the mid thoracic spine again demonstrated . Clips in the left axilla are again noted .
    OUTPUT:
    
Small bilateral pleural effusions with slight interval increase in loculated pleural fluid about the right lung apex . Patchy opacity within the right lung base may reflect asymmetric pulmonary edema though infection can not be excluded .
