Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The patient is status post median sternotomy and CABG . Single - lead left - sided pacemaker is again seen with lead extending to the expected position of the right atrium . The cardiac silhouette remains enlarged . The aorta remains calcified and tortuous . Bilateral interstitial opacities and central vascular prominence is stable compared to the prior study suggesting mild interstitial edema . Posterior basilar opacity on the lateral view is grossly similar as compared to the study from ___ and may represent atelectasis / scarring although infection is not excluded in the appropriate clinical setting . The right costophrenic angle remains blunted on the frontal image . Mild biapical pleural thickening with calcification . No definite fracture is seen , although evaluation is not optimal for such . This study does not well assess the spine . If there is clinical concern for spine or rib fracture , dedicated imaging of the spine or ribs should be obtained .
    OUTPUT:
