Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Extreme left lung base the left costophrenic angle excluded from the film . Again seen is an ET tube , with tip approximately 3 .7 cm above the carina . An NG tube is present -- although poorly delineated in the lower mediastinum , it likely extends beneath the diaphragm stop , similar to prior . Additional wires and leads overlie the chest . Again seen is cardiomegaly . There is upper zone redistribution and diffuse vascular blurring , consistent with CHF . There more confluent opacities at left - greater - than - right lung bases , similar to prior . Probable left effusion , though this is not well visualized due to positioning of the film edge . Extreme right costophrenic angle excluded from the film , but no gross right effusion . No pneumothorax detected .
    OUTPUT:
    
Cardiomegaly . CHF findings are probably slightly worse compared with 1 day earlier . Bibasilar opacities are similar to prior . Persistent left effusion .
