Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ___ radiograph shows a single lead from a left pectoral pacemaker projecting over the right ventricle . There is no pneumothorax . A right PICC line terminates in the upper right atrium near the cavoatrial junction . Withdrawal by 1 - 2 cm would position its tip at the cavoatrial junction if desired . Mild pulmonary edema has slightly increased . Moderate cardiomegaly despite the projection is unchanged . A small left pleural effusion is likely present . Increased retrocardiac airspace opacification may be due to atelectasis or infection . Previous cervical spine fusion is partially imaged . The followup PA and lateral radiographs from ___ confirm a left lower lobe airspace opacity , which is most likely due to pneumonia . There is also increased mild pulmonary edema .
    OUTPUT:
    
New left pectoral pacemaker with single lead projecting over the right ventricle . No pneumothorax . New left lower lobe pneumonia . Increase mild pulmonary edema . Right PICC line tip approximately 2 cm below the estimated location of the cavoatrial junction .
