Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided pacer device is noted with leads terminating in the right atrium and right ventricle . Right - sided Port - A - Cath tip terminates in the low SVC , unchanged . Bilateral chest tubes are in similar positions . A moderate size right pleural effusion has increased from the prior study and is loculated laterally . Small left pleural effusion appears somewhat decreased compared to the prior study . Opacities in both lung bases likely reflect regions of compressive atelectasis . Cardiac and mediastinal contours are unchanged . Pulmonary vasculature is not engorged . No definite pneumothorax is detected . There are no acute osseous abnormalities .
    OUTPUT:
    
Interval increase in size of right pleural effusion , now moderate , and loculated laterally . Small left pleural effusion appears perhaps minimally decreased from prior . Bilateral chest tubes in place . Bibasilar airspace opacities likely reflect compressive atelectasis , however infection can not be excluded in the correct clinical setting .
