Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged . No typical configurational abnormality is identified . Thoracic aorta is moderately widened and shows calcium deposits in the wall , mostly at the level of the arch . No local contour abnormalities are identified . The pulmonary vasculature is not congested . The diaphragms are relatively low positioned and flattened , a finding which in conjunction with the irregular distribution of the pulmonary peripheral vasculature is indicative of COPD . Acute parenchymal infiltrates , however , can not be identified . Also , the lateral and posterior pleural sinuses are free from any fluid accumulation . There is evidence of at least two rib deformities in the right hemithorax related to the fourth , fifth and sixth ribs in the posterior lateral circumference and most likely representing old healed rib fractures . The lateral chest view discloses an accentuated kyphotic curvature in the thoracic spine with moderate degree of degenerative changes , but no conclusive evidence of any vertebral body compression fracture .
    OUTPUT:
    
Stable chest findings in comparison with previous chest examinations of ___ and ___ . There is no evidence of acute pulmonary infiltrates or acute pulmonary congestion .
