Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . There is significant cardiac enlargement . The configuration suggests prominence of the left ventricular contour to the left and posteriorly . There is also probably some mild left atrial enlargement . The thoracic aorta is generally widened and elongated but does not demonstrate local contour abnormalities . The pulmonary vasculature demonstrates an upper zone re-distribution pattern , but no evidence of significant interstitial or alveolar edema is present . The lateral and posterior pleural sinuses are free and there are no acute pulmonary infiltrates . No pneumothorax in the apical area . Skeletal structures demonstrate some degree of demineralization of the vertebral bodies of the thoracic spine as seen in the lateral view , but there is no evidence of any vertebral body compression fracture . Prominent soft tissue structures surrounding the thorax indicative of advanced obesity . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
Cardiac enlargement , mild degree of pulmonary congestion , but no pleural effusion or acute infiltrates in this ___-year - old female patient who developed atrial fibrillation .
