    INPUT: Right internal jugular central venous catheter tip terminates in the mid SVC . Right - sided AICD device lead terminates in the right ventricle , unchanged . Patient is status post median sternotomy and CABG . Heart size remains moderately enlarged . The aorta is tortuous and diffusely calcified . Mild pulmonary vascular congestion is minimally improved . There are persistent small bilateral pleural effusions , larger on the right . More focal patchy opacities in lung bases may reflect atelectasis but infection is not excluded . No pneumothorax is identified .
    OUTPUT:
