Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest was obtained with patient in supine position . Comparison is made with the next preceding portable chest examination of ___ . On the present image , the patient is intubated with the ETT terminating in the trachea 4 cm above the level of the carina . No pneumothorax has developed . Overlying cables and electrodes appear to be external . Identified is a catheter approached from below passing the right atrium and the right ventricular outflow tract so to terminate in the proximal portion of the left pulmonary artery . A second external device consists of an intra-aortic balloon pump device that terminates appropriately in the upper portion of the descending aorta . Its termination point is just below the expected lower contour of the aortic arch . Chest findings have changed dramatically since the preceding chest examination of ___ when the patient was in acute advanced pulmonary edema with additional evidence of bilateral pleural effusions . Pleural effusions have disappeared as at least on the supine image the lateral pleural sinuses are completely free . Lungs demonstrate still a typical pulmonary edema pattern with subtle haze bilaterally in the central lung regions . These findings , however , have improved markedly and there is no evidence of any remaining peripheral pulmonary parenchymal infiltrate . No pneumothorax is present in the apical area . The overall heart size is presently not significantly enlarged as can be identified on a single portable chest view . An NG tube is also seen to reach well below the diaphragm including its side port .
    OUTPUT:
    
Marked improvement of patient previously in acute cardiac distress with pulmonary edema . Mild degree of pulmonary edema persists . Further followup examinations may be helpful to monitor degree of remaining edema .
