Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal portable radiograph demonstrates a left subclavian approach central venous catheter with tip in cavobrachiocephalic junction . An enteric tube traverses inferiorly out of view . The lung volumes remain low , accentuating massive enlargement of cardiac silhouette , which could reflect a component of a failure and / or pericardial effusion . Perivascular congestion is mildly improved . Right upper lung opacity is re-demonstrated , compatible with underlying chronic apical mass . Left lower lobe consolidation is re-demonstrated , likely associated with a component of atelectasis . Small bilateral pleural effusions are not excluded .
    OUTPUT:
    
Minimal interval improvement of vascular congestion . Persistent massive cardiomegaly could reflect cardiac decompensation versus pericardial effusion . Persistent left lower lobe consolidation and right upper lobe opacity .
