Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest was obtained . A dual - lead left - sided pacemaker is seen with leads in the expected position of the right atrium and right ventricle . There are low lung volumes , which accentuate the bronchovascular markings . Bibasilar , left greater than right opacities may be due to atelectasis , although aspiration or infection are also possibilities . Patchy medial right upper lobe opacity may relate to overlapping structures with anterior right first rib , although underlying consolidation from aspiration not excluded . There is prominence of the central vasculature consistent with pulmonary vascular congestion . No large pleural effusion or pneumothorax . The cardiac silhouette is top normal . The aorta is calcified .
    OUTPUT:
    
1 . Low lung volumes , which accentuate the bronchovascular markings . Left greater than right bibasilar opacities could relate to aspiration in the appropriate clinical setting , although may be due to atelectasis or alternatively infection . 2 . Pulmonary vascular congestion .
