Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest was obtained . The cardiac silhouette is enlarged due to cardiomyopathy and / or pericardial effusion . Patient is status post median sternotomy . A dual - lead left - sided pacer device is seen . The distal aspect of the leads are not seen due to underpenetration at the lower hemithorax . The hemidiaphragms are partially obscured but could relate to underpenetration , although there may also be a right - sided pleural effusion with underlying atelectasis , underlying consolidation can not be excluded . There is mild prominence of the central pulmonary vasculature which could in part relate to low lung volumes . No pneumothorax is seen .
    OUTPUT:
    
Underpenetration of the lung bases which may be related to patient body habitus , and low lung volumes make exam suboptimal . Given this , opacity at the right lung base could be due to pleural effusion and atelectasis , underlying consolidation not excluded . Left base retrocardiac opacity seen may also be due to atelectasis and / or consolidation . Mild central pulmonary vascular prominence . Enlarged cardiac silhouette .
