Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient 's condition required examinations in sitting semi-upright position using AP frontal and left lateral views . Comparison is made with a similar preceding study of ___ . The heart size has increased and bilateral basal densities are now obscuring diaphragmatic contour and blunting the lateral pleural sinuses . The lateral view confirms the bilateral pleural effusions that have increased and blunting the posterior pleural sinuses more than before . Within the heart shadow , there are rather typical calcifications within the aortic valve area strongly suggesting the presence of aortic valve stenosis . Additional linear calcifications in the ascending aorta are seen as before . No new abnormalities in the pulmonary parenchymal area and skeletal structures are unchanged . Several preceding chest examinations are reviewed and include studies of ___ , ___ , and ___ . A previously suspected calcification on the right lung base was identified as being located in the right breast . Thus , there is no evidence of new acute or old chronic pulmonary parenchymal abnormalities . On the previous examinations , the rather typical aortic valve calcifications were also noted but reported apparently as this finding was of no greater importance in this elderly demented patient .
    OUTPUT:
    
Evidence of bilateral pleural effusion , increasing heart size indicative of chronic CHF . No evidence of pneumonia .
