Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , and there is moderate cardiomegaly , with indistinct pulmonary vasculature , consistent with moderate pulmonary edema . The left - sided pacemaker leads project in the right atrium and right ventricle . A left pleural effusion is moderate , with overlying patchy opacity , potentially atelectasis though infection can not be excluded . Streaky right basilar atelectasis is mild with associated small right pleural effusion . No evidence of pneumothorax . A vascular stent projects over the left upper lung . The aorta is extensively calcified .
    OUTPUT:
    
1 . Moderate cardiomegaly , moderate left - sided and small right - sided pleural effusions , and moderate pulmonary edema , findings compatible with congestive heart failure . No pneumothorax detected . 2 . Left basilar patchy opacity may reflect atelectasis but infection is not excluded in the correct clinical setting .
