Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post coronary artery bypass graft surgery . The heart is at the upper limits of normal size . The aortic arch is partly calcified . The pulmonary vasculature is minimally prominent suggesting pulmonary venous hypertension or slight congestion without frank congestive heart failure . There is also a patchy right infrahilar opacity , suspected to represent minor streaky atelectasis . A linear opacity seen posteriorly on the lateral view probably is due to stable scarring in the left lower lobe . There are no pleural effusions or pneumothorax . Thin anterior flowing syndesmophytes are present along the lateral and anterior aspects of the visualized thoracic spine , which could be seen with idiopathic skeletal hyperostosis .
    OUTPUT:
    
1 . Findings suggesting minimal congestion or pulmonary venous hypertension , new on this study . 2 . Patchy right basilar opacity suspected to represent minor atelectasis .
