Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged . Surgical clips project over the left lower hemithorax , probably in the left breast . There is moderate unfolding of the thoracic aorta . The aortic arch is partly calcified . The mediastinal and hilar contours appear unchanged . The right costophrenic angle is partly excluded posteriorly but there is no evidence for pleural effusions . A widespread interstitial abnormality , somewhat more prominent on the right than left , appears worse than on the most recent prior radiographs and suggest mild - to - moderate interstitial pulmonary edema . A supportive finding is the presence of Kerley B lines in the right cardiophrenic angle on the frontal view .
    OUTPUT:
    
Mild - to - moderate pulmonary vascular congestion .
