Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral chest radiographs again demonstrate a dilated thoracic aorta and sternal wires and surgical clips projecting over the right mediastinum compatible with prior ascending aortic dissection repair . The cardiac silhouette size is top normal . Mediastinal contour is otherwise unchanged . Somewhat rounded opacity projecting over the right lung base is likely related to prior talc pleurodesis , as seen on the previous examination . There is no new focal consolidation , pleural effusion , or pneumothorax is identified . Median sternotomy wires are intact . The visualized upper abdomen is unremarkable . Moderate degenerative changes are noted in the thoracic spine .
    OUTPUT:
    
Status post ascending aortic dissection repair without evidence for acute cardiopulmonary abnormality .
