Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right internal jugular central venous catheter ends in the low SVC , as before . A pleural catheter continues to end at the left lung base , although the distal end of the catheter has lost its previously seen pigtail configuration . Lung volumes remain slightly low . Dense left retrocardiac atelectasis is not significantly changed . Scattered heterogeneous opacities throughout the remainder of the left lung are subsegmental atelectasis , possibly related to splinting in the setting of multiple unchanged left - sided rib fractures . There is no definite pneumothorax . A small left pleural effusion is not significantly changed . There are increased right lower lung heterogeneous opacities , likely asymmetric pulmonary edema versus early pneumonia . The heart size is mildly enlarged , increased compared to the prior study from ___ . The mediastinal contours are unchanged . The stomach is mildly distended with air .
    OUTPUT:
    
1 . Findings concerning for early cardiac decompensation , including increased mild cardiomegaly , possible asymmetric right lower lobe interstial edema , and an unchanged small left pleural effusion . 2 . Possible early right lower lobe pneumonia , more likely asymmetric edema as previously discussed . 2 . Dense left retrocardiac atelectasis , not significantly changed . 2 . Left pleural catheter unchanged in position , although the pigtail is now uncoiled . No definite pneumothorax . Findings were discussed with Dr . ___ by Dr . ___ ___ telephone at 12 :46 p .m . on the day of the study .
