Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable chest radiograph demonstrates interval removal of Swan - Ganz catheter and ETT and remaining right - sided central venous sheath with tip terminating in the upper SVC . There is stable cardiomegaly with improving postoperative pneumopericardium . No chest tubes or mediastinal drains are evident . A fold is identified crossing left ribs ___ , possibly a pleural fold due to small apical pneumothorax ; however , unable to assess for lung markings beyond this fold due to overlying medical devices . There is redemonstration of prominent interstitial markings and hazy vascular consistent with pulmonary edema with increased lucency in the left upper lobe . However , unclear if this is related to possible pneumothorax or improved aeration . Trace pneumoperitoneum newevident and may be due to previous reported pneumopericardium . Please correlate with any abdominal surgical history , instrumentation and clinical exam . Slightly increased retrocardiac opacity may reflect a combination of atelectasis and pleural effusion though in the appropriate clinical setting , infectious process can not be excluded .
    OUTPUT:
    
1 . Possible left apical pneumothorax . Recommend repeat upright chest radiograph . Resolving pneumopericardium , though pneumoperitoneum is evident , possibly related to air leak . Please correlate with clinical exam . 2 . Increased retrocardiac opacity , possibly a combination of effusion and atelectasis , though an infectious process can not be excluded . 3 . Stable pulmonary edema . 4 . Interval removal of endotracheal tube . ___ communicated these findings to ___ , NP at 11 :45 via telephone on ___ .
