Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient upright position . Analysis is performed in direct comparison with the next preceding available chest examination ___ ___ . The heart size is at the upper limit of normal variation . No typical configurational abnormality is seen , however , there is a relative prominence of the left ventricular contour to the left and posteriorly . The thoracic aorta is of unchanged and ordinary ___ . No mediastinal abnormalities are present . The pulmonary vasculature is not congested . No acute parenchymal infiltrates can be identified . Similar as on the preceding study , there exists a peripheral linear density with some crowded vasculature in the lower left lung fields abutting the cardiac contours and compatible with the previously made suggestion of an atelectasis in the lingula . The appearance of these findings is completely unchanged and suggests scar formations of previous inflammatory processes . An additional subtle change is the more prominent visibility of the minor fissure on the right side , possibly suggestive of mild beginning pulmonary congestion with lung wetness of the subpleural spaces . Significant pleural effusions in the lateral or posterior pleural sinuses , however , can not be identified . The lateral view discloses again relatively low positioned and flattened diaphragms , a finding consistent with the patient 's diagnosis of COPD .
    OUTPUT:
    
No evidence of new acute pulmonary parenchymal infiltrates . Although a very subtle finding , the increased visibility of the minor fissure is suggestive of possible beginning pulmonary congestion in this patient with a borderline heart size . It is therefore recommended to address patient 's cardiac function which may be the cause of beginning mild degree of chronic pulmonary congestion .
