Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . The heart size is mildly enlarged . The configuration suggests a prominence of the left ventricular contour to the left and posteriorly , but there is also some evidence of left atrial enlargement in the form of a right - sided cardiac double contour and prominence of the heart shadow at the atrial level as seen on the lateral view . The pulmonary vasculature demonstrates an upper zone re-distribution pattern with relatively distended pulmonary vessels in the upper zone and some beginning increased interstitial structures on the lung bases . There is very mild blunting of the right lateral pleural sinus and a similar finding is noted on the lateral view . Acute discrete pulmonary parenchymal infiltrates are not present , nor is there evidence of central pulmonary edema . No pneumothorax is seen in the apical area . Skeletal structures of the thorax are grossly unremarkable . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
Mild cardiac enlargement with evidence of beginning pulmonary congestion . Findings compatible with diastolic CHF , resulting in mild degree of pulmonary congestion . Followup examination after treatment could demonstrate reversal of beginning pulmonary congestive pattern .
