Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen is the right IJ single pacing lead with tip over right ventricle . Inspiratory volumes are considerably lower . Again seen is left lower lobe collapse and / or consolidation . A small left effusion would be difficult to exclude . The vascular markings are prominent , more so than on the previous film , but likely accentuated by low lung volumes . Minimal atelectasis at the right base . Heart borders are obscured by left base opacity , but grossly unchanged .
    OUTPUT:
    
1 . Left lower lobe collapse and / or consolidation , probably slightly worse . 2 . Vascular plethora , suggestive of CHF , but likely accentuated by low lung volumes .
