Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ETT tube , NG tube , and right and left IJ lines are similar to the prior study . Again seen is the left chest tube . The sideport now lies slightly more proximal / lateral , partially overlying the left chest wall , suggesting slight interval retraction . Allowing for this , the appearance of left lung is grossly unchanged , with increased retrocardiac density , hazy density along the left chest wall , and fluid tracking along the left lung apex . Suspect left pleural effusion . No left - sided pneumothorax or subcutaneous emphysema along the left chest wall . The appearance of the right lung is also similar , with evidence for interstitial edema , hazy opacity at the right base , and probable small effusion . Lucency previously seen along the right chest wall raising the possibility of a skin fold versus pneumothorax is no longer visualized . No evidence of right - sided pneumothorax is detected on the current study . Cardiomegaly , prosthetic valve , and sternotomy wires , are similar to prior . There is CHF , with interstitial and probable alveolar edema , which may be very slightly improved compared 1 day previous . Again seen is an iatrogenic linear density , with tip overlying the lateral border of the scapula . The appearance is suggestive of a PICC line , though note is made that is not that it does not extend into the chest itself . The appearance is unchanged compared with ___ at 13 44 .
    OUTPUT:
    
Suspect very slight interval retraction of left chest tube . The appearance of the left chest , however , is grossly unchanged compared 1 day earlier . Pulmonary edema , with possible slight improvement compared with 1 day earlier . Linear lucency along right chest wall no longer visualized --___ presumably represented artifact due to a skin fold . Otherwise , the appearance of the right chest is grossly unchanged . No pneumothorax detected . Linear density with tip overlying lateral border right scapula , unchanged . Clinical correlation is requested . The appearance is suggestive of a PICC line . However , it does not reach the expected location of the right subclavian vein and does not extend into the chest itself .
