Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left chest cardiac device with associated dual leads overlying the right atrium and ventricle is noted . The cardiac silhouette is mildly enlarged . Aortic arch calcifications are noted . The hila are within normal limits . There is likely a trace right pleural effusion . There is blunting of the left lateral costophrenic angle extending superiorly with a configuration suggesting component of effusion , potentially loculated or with associated pleural thickening . Best seen on the lateral view is increased opacity seen posteriorly over the mid thoracic spine with a suspected air-fluid level superiorly . There is diffuse chronic interstitial abnormality which may reflect sequelae of underlying chronic lung disease or chronic pulmonary edema . Retrocardiac opacity likely reflects atelectasis . Otherwise , there is no focal lung consolidation . There is pleural parenchymal scarring at the lung apices .
    OUTPUT:
    
1 . Small right pleural effusion and suspected moderate left pleural effusion which may be loculated or associated with pleural thickening . 2 . Opacity seen posteriorly on the lateral view with a suspected air-fluid level raising possibility of a loculated hydropneumothorax . 3 . Diffuse pulmonary interstitial abnormality may reflect sequelae of chronic edema . Currently , no overt pulmonary edema .
