Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Perihilar distribution of opacities consistent with pulmonary edema . Opacities somewhat obscure mediastinal and hilar contours , though there are no gross contour abnormalities evident . Bilateral large pleural effusions with dense opacification in the lung bases likely reflecting adjacent compressive atelectasis , though can not exclude pneumonia in the appropriate clinical setting . Minimally displaced rib fractures evident in the right posterior sixth and seventh ribs as well as possible non-displaced fractures in the eighth and ninth ribs . Rib fractures were better evaluated on concurrent CT . The patient is status post CABG with sternotomy sutures midline and intact . There is dense mitral annular calcification identified as well as aortic valve replacement . Pacemaker leads tips are positioned in the right atrium and right ventricle .
    OUTPUT:
    
Moderate to severe pulmonary edema and bilateral pleural effusions . Multiple right posterior fractures as described above .
