Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Poor inspirational effort results in rather high positioned diaphragms with thereto related crowded appearance of pulmonary vasculature on the bases . Major portions of the heart shadow are concealed ; however , some moderate cardiac enlargement appears to be present . Thoracic aorta is mildly elongated , but does not show any local contour abnormalities . In the pulmonary vasculature , an upper zone redistribution pattern is noted , but there is absence of any advanced interstitial or alveolar edema . Also , the lateral and posterior pleural sinuses remain free of any fluid accumulation and there is no pneumothorax in the apical area on either side . The thoracic spine demonstrates a moderate degree of S - shaped scoliosis with more prominent convexity to the left on the base . No other significant skeletal abnormalities are noted . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
Mild cardiac enlargement , poor inspirational effort and crowded appearance of pulmonary vasculature with possible upper zone redistribution pattern , but absence of advanced congestion and no pleural effusion . The findings most likely represent mild cardiac enlargement with mild degree of pulmonary congestion . Cardiac evaluation or followup chest examination is recommended . No acute infiltrates of inflammatory nature are identified .
