Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy , with prominence of the cardiomediastinal silhouette . Due to underpenetration , the tip of the ET tube is not well delineated . It appears to lie in satisfactory position approximately 4 .6 cm above the carina . No definite NG tube . A left subclavian central line tip overlies the distal SVC . No obvious pneumothorax . Hazy opacity at the right base likely reflects a small effusion with underlying collapse and / or consolidation . Partial interval clearing at the left base , but retrocardiac opacity and very hazy density persists . There is upper zone redistribution and diffuse vascular blurring , consistent with mild CHF . The patient 's spinal hardware and sternotomy wires and mediastinal clips again noted .
    OUTPUT:
    
1 ) ET tube tip in satisfactory position approximately 4 .6 cm above the carina . 2 ) CHF , interstitial edema , and right effusion with underlying collapse and / or consolidation . 3 ) Partial interval clearing at the left base , but retrocardiac opacity and very hazy density persists .
