    INPUT: AP view of the chest was obtained . There is a single lead left - sided AICD with lead in the expected position of the right ventricle , unchanged . The cardiac silhouette is moderately moderately enlarged , appears increased in size since the prior study , may in part relate to technique . There is no overt pulmonary edema . Previously noted medial right base opacity is still seen , but less apparent than on the prior study and most likely relates to vascular structures . Findings could be better evaluated with PA and lateral views if patient able . No new focal consolidation is seen . There is no evidence of large pleural effusion or pneumothorax .
    OUTPUT:
