Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in supine position . No preceding chest examination is available for comparison . A right subclavian approach line is seen apparently related to a most recent Port - A - Cath system placement . The line terminates at the level 6 cm below the carina , and related to the demonstrated external cardiac contours , it may have reached the upper portion of the right atrium . The heart does not appear enlarged , and no configurational abnormality is identified . There is no pulmonary vascular congestion , and no pleural effusions that are blunting the lateral pleural sinuses . No pneumothorax in the apical area . Surgical clips in the mid portion of the upper abdomen , indicative of previous surgery , type unknown .
    OUTPUT:
    
Tip of Port - A - Cath line reaching in upper portion of right atrium . This is not an unusual finding and appears well tolerated as the Port - A - Cath lines are not very flexible . If the purpose is to terminate in the lower SVC , withdrawal of the line by 3 cm is recommended .
