Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided PICC line terminates in the superior vena cava . Again noted is a dual - lead pacemaker / ICD device , which appears unchanged . The heart is mildly enlarged . The mediastinal and hilar contours are stable . The right - sided pleural effusion appears decreased , but there is again a predominantly central widespread interstitial abnormality with indistinct pulmonary vasculature , most consistent with moderate - to - severe pulmonary edema . In addition , the left hemidiaphragm is obscured by retrocardiac opacity , although not completely specific , most often due date coinciding atelectasis .
    OUTPUT:
    
Fairly similar degree of pulmonary edema compared to the last visit . Persistent small - to - moderate right - sided pleural effusion , although decreased , but with persistent non-specific retrocardiac opacification .
