Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Multiple lines and tubes been removed . No definite pneumothorax is identified . Note is made of a developmental variant . This is not fully evaluated on this examination , but apparently consists of enlarged bilateral C7 ribs that articulate with the ribcage antero laterally . No clear articulation with the scapula or scapular deformity is detected . If is associated with a bell - shaped thoracic cage . There is moderate to moderately severe cardiomegaly , with sternotomy wires and prosthetic valves noted . The mediastinum is also slightly prominent in the cardiomediastinal silhouette is slightly indistinct . This appearance is slightly improved compared with ___ including very slight interval improvement in the degree of cardiomegaly . There is patchy opacity at the right lung base . , significantly increased compared with ___ . No gross right effusion . There is also patchy opacity at the left lung base , associated with slight improvement in the amount of retrocardiac density . The left hemidiaphragm remains obscured . The left costophrenic angle is slightly blunted , but better seen . There is slight upper zone redistribution and mild vascular plethora , without other evidence of CHF .
    OUTPUT:
    
No pneumothorax detected status post removal multiple lines and tubes . Note is made that the lung apices are partially obscured by a developmental anomaly involving cervical ribs . Enlargement of the cardiomediastinal silhouette , compatible with recent surgery , slightly improved . Right suprahilar patchy opacities noted to the improved . Increase patchy opacity at the right base . Curvilinear appearance suggests some platelike atelectasis . An early infiltrate is considered less likely but can not be entirely excluded . Slight interval improvement in the left lower lobe collapse and / or consolidation . Small bilateral effusions can not be excluded . Upper zone redistribution and mild vascular plethora , without other evidence of CHF .
