Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left PICC remains in place , coursing within a left - sided superior vena cava , unchanged in position . Persistent moderate cardiomegaly is accompanied by pulmonary vascular congestion and mild interstitial edema . Small right pleural effusion is present with adjacent patchy posterior basilar opacity . In addition to the dependent pleural effusion , there is a suggestion of a focal loculation laterally in the mid portion of the right chest , although prominent extrapleural fat probably contributes to this appearance .
    OUTPUT:
    
1 . Cardiomegaly and congestive heart failure . 2 . Small right pleural effusion with possible component of loculation laterally . Adjacent dependent right lower lobe opacity may reflect atelectasis , but pneumonia should also be considered in the appropriate clinical setting .
