Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to the prior study , there are minimally increased bibasilar interstitial opacities likely reflecting atelectasis . Otherwise , little interval change . There is upper zone redistribution , unchanged , but no overt CHF . No focal consolidation or effusion identified . Triple - lead ICD device again noted . ( Inferior extent of heart and inferior most lead excluded from this film . ) There is mild to moderate cardiomegaly , with an unfolded aorta . Calcifications projecting over the left ventricle are suggestive of prior infarction . There is prominence of the pulmonary hila , with a tapered configuration , probably unchanged , which may reflect pumonary hypertension .
    OUTPUT:
    
1 ) Upper zone redistribution , unchanged . Doubt overt CHF . 2 ) Mild bibasilar atelectasis , which is new . No frank consolidation . 3 ) ICD device . Stable cardiomegaly . Calcifications along left ventricular wall suggestive of prior infarct -- see also abdominal CT from ___ . 4 ) Stable prominence of hila - ? pulmonary hypertension .
