Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube has been retracted slightly and now resides approximately 5 cm above the carina . There is a new left subclavian central venous catheter that terminates in the upper superior vena cava . An orogastric tube again courses through the mediastinum into the left upper quadrant . The cardiac , mediastinal and hilar contours appear unchanged . There is no pleural effusion or pneumothorax . Vague left mid lung opacity suspected on the prior study is less distinct , but there may be a developing retrocardiac opacity at the medial left lung base , where opacity appears somewhat denser . Patchy right basilar opacity is likely due to minor atelectasis and appears unchanged .
    OUTPUT:
    
Status post interval placement of left subclavian central venous catheter with tip terminating in the superior vena cava . Interval retraction of endotracheal tube . Suspicion for developing medial left basilar opacity , for which further attention in follow - up imaging is recommended .
