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 . The patient is now intubated , the ETT seen to terminate in the trachea 4 cm above the level of the carina . A right internal jugular vein sheath is noted to reach with its tip 1 cm below the lower edge of the clavicle . This is close to the junction of the jugular and subclavian veins . New row of midline sternal wires indicates recent cardiac surgery . Multiple external wires are overlying the chest . There is a semi-circular metallic structure in the expected area of the tricuspid valve and probably relates to an annuloplasty . Heart size remains enlarged with considerable prominence of the right atrial contour to the right . Pulmonary vasculature is slightly increased , but there is no evidence of large pleural effusions and no pneumothorax is seen in the apical area .
    OUTPUT:
    
Satisfactory first post-operative chest findings .
