Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest was obtained . There has been interval placement of a left - sided pacer device with a lead seen extending to the expected location of the right ventricle and the coronary sinus . There may also be a lead extending to the right ventricle , although this is not well seen on the current study . Right lower hemithorax opacity is seen which may be due to underlying subpulmonic effusion with overlying atelectasis , although underlying consolidation is not excluded . Findings may also be due to elevation of the right hemidiaphragm . If patient able , suggest dedicated PA and lateral views for better evaluation . There is prominence and indistinctness of the hila . The cardiac silhouette remains enlarged . Patient is status post median sternotomy .
    OUTPUT:
    
Enlarged cardiac silhouette and engorged pulmonary hila with pulmonary vascular congestion may be due to CHF . Right lower hemithorax opacity could be due to pleural effusions with overlying atelectasis and / or consolidation , elevation of the right hemidiaphragm . If patient able , dedicated PA and lateral views would be helpful for further evaluation .
