Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to the prior film , I doubt significant interval change . Again seen is an ET tube , approximately 4 .6 cm above the carina ; an NG tube , with tip overlying gastric fundus ; bilateral chest tubes ; a mediastinal drain ; and a Swan - Ganz catheter , with tip over the proximal right pulmonary artery . No pneumothorax detected . The patient is status post sternotomy , with prosthetic valve . The cardiomediastinal silhouette is probably unchanged , allowing for technical differences . Again seen is left lower lobe collapse and / or consolidation and mild vascular plethora , without overt CHF .
    OUTPUT:
    
Doubt significant change compared with ___ . A small left effusion would be difficult to exclude . No right - sided effusion is identified .
