Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a single - lead pacemaker / ICD device whose lead terminates in the right ventricle as before . The tricuspid and aortic valves has been replaced . Hazy opacities that are predominantly central within each lung suggest mild pulmonary edema . A persistent pleural effusion with loculated character appears unchanged on the right , with probable atelectasis opacifying a substantial portion of the right lower hemithorax , as before . There is probably a trace pleural effusion only on the left . No pneumothorax is demonstrated .
    OUTPUT:
    
Findings suggesting mild pulmonary edema . Similar moderate - sized right pleural effusion , probably loculated to some extent , with persistent lung opacification that can probably be attributed to associated atelectasis .
