Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided AICD / pacemaker device is noted with leads terminating in the right atrium and right ventricle . The patient is status post median sternotomy and CABG . Moderate cardiomegaly is re- demonstrated , and the mediastinal contours are unchanged . Worsening alveolar opacities are noted predominant within the right mid lung field and left lung base . Continued vascular indistinctness and perihilar haziness is again seen . These findings likely reflect worsening moderate pulmonary edema , though developing areas of infection in the right mid lung field and left lung base can not be completely excluded . Small bilateral pleural effusions are noted . There is no pneumothorax . No acute osseous abnormalities demonstrated .
    OUTPUT:
    
Moderate pulmonary edema , worse in the interval , though developing areas of infection in the right mid lung field and left lung base can not be completely excluded . Followup radiographs after diuresis are recommended . Small bilateral pleural effusions .
