Compared to prior chest radiographs since , most recently .
 
 Severe cardiomegaly is chronic.  Mediastinal veins were acutely distended and

 and .
 
 Today lung volumes have improved, edema has decreased, but the severe
 cardiomegaly and mediastinal venous engorgement are still present.  Pleural
 effusions are presumed, but not large.
