Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube tip projects approximately 5 .1 cm above the carina . Right IJ Swan - Ganz catheter tip is unchanged in position . Left IJ central line tip is unchanged , extending to the junction of the brachiocephalic vein and superior vena cava . Pacer lead tip projects in the region of the right ventricle . Positioning of the LVAD is unchanged . The prior left chest tube is unchanged in position , with interval decrease in the amount of pleural fluid . Increased aeration of the bilateral lower lungs . Diffuse bilateral pulmonary opacifications persist . Moderate severe cardiomegaly is unchanged .
    OUTPUT:
    
1 . Unchanged positioning of multiple lines and tubes and the LVAD . The endotracheal tube terminates 5 .1 cm above the carina . 2 . Previous bilateral pulmonary opacifications are persisting , but have cleared , predominantly in the lower lobes . Therefore , superimposed pneumonia in the upper lobes is not excluded in the appropriate clinical setting .
