Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy , with apparent prosthetic valve . A left IJ central line tip overlies the distal SVC . No pneumothorax is detected . There is cardiomegaly , similar to the prior film . There is upper zone redistribution and diffuse vascular plethora , slightly more pronounced than on the prior film . There is increased retrocardiac density , consistent with left lower Lat left lower lobe collapse and / or consolidation , similar to the prior film . As before , the possibility of a left - sided effusion can not be excluded . On the right , there is opacity at the right lung base , suggestive of a right pleural effusion with underlying collapse and / or consolidation , also overall similar to the prior film . A pigtail catheter overlies the right mid abdomen .
    OUTPUT:
    
1 . Vascular plethora with interstitial and probable early alveolar edema , slightly more pronounced than on the prior film . 2 . Cardiomegaly with right and question left pleural effusion and underlying collapse and / or consolidation , similar to the prior study . 3 . No pneumothorax detected .
