Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with the prior film , the ET tube and NG tube have been removed . The left chest tube has also been removed . Additional linear densities are seen over the upper abdomen , but the mediastinal drain and right chest tube may very well have been removed . No pneumothorax is detected . The right IJ Swan - Ganz catheter is again seen . The tip as been retracted and now overlies the proximal right main pulmonary artery . The patient is status post sternotomy , with cardiomegaly , which appears unchanged . The possibility of pericardial fluid can not be excluded . There is persistent increased retrocardiac density with obscuration left hemidiaphragm , consistent with left lower lobe collapse and / or consolidation . There is also persistent hazy opacity in the right cardiophrenic region . No right side no significant right - sided pleural effusion . The possibility of a small left effusion can not be excluded . Minimal upper zone redistribution , but no overt CHF . Note is again made of a normal variant azygos fissure . Much of the detail visible on the ___ chest CT is not apparent radiographically .
    OUTPUT:
    
1 . Cardiomediastinal silhouette is enlarged , but unchanged . 2 . No pneumothorax detected . No gross effusion . A small left effusion would be difficult to exclude . 3 . Persistent left lower lobe collapse and / or consolidation . Persistent patchy right cardiophrenic opacity . 4 . No overt CHF . 5 . No pneumothorax detected status post removal of chest tube .
