Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval removal of a right internal jugular transvenous pacer from ___ but a right IJ sheath is in place with the tip terminating in the upper SVC at its origin . A left pectoral pacemaker has been placed in the interval from the prior study with two leads , which appear to terminate in the right atrium and in the apex of the right ventricle on this single frontal view . The inspiratory lung volumes remain low , which accentuates the appearance of the cardiomediastinal silhouette . Allowing for this , the cardiac silhouette is enlarged but stable . Mild engorgement of the pulmonary vessels is unchanged . Mild diffuse opacification of the bilateral lungs , greater on the right than the left , likely reflects a combination of mild pulmonary edema and subsegmental atelectasis . Retrocardiac opacification at the left lung base is consistent with volume loss in the lower lobe . Small pleural effusions are present bilaterally . No pneumothorax is detected . There is significant S - shaped thoracolumbar scoliosis .
    OUTPUT:
    
1 . Appropriate placement of dual pacemaker leads . 2 . Small bilateral pleural effusions in combination with mild pulmonary edema suggest congestive heart failure . 3 . Left lower lobe volume loss and subsegmental atelectasis .
