Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left pectoral pacemaker is again seen with the leads in unchanged position projecting over the right and left ventricles . Since the prior exam , there is increased vascular congestion and interstitial opacities , consistent with mild pulmonary edema . There is a persistent opacity on the right , which may reflect atelectasis , although in the proper clinical setting , pneumonia is a consideration . There are small bilateral pleural effusions . There is no pneumothorax . The mediastinal contours are normal . The heart is moderately enlarged , and very slightly increased in size from the prior exam .
    OUTPUT:
    
1 . New mild pulmonary edema . Slight interval increase in cardiac size , likely due to cardiomegaly , although a pericardial effusion is a consideration . 2 . Right basilar consolidation , possibly due to atelectasis . In the proper clinical setting , a pneumonia can not be excluded .
