    INPUT: There has been interval removal of the right central venous catheter . Bibasilar pulmonary opacities , left greater than right , appear similar compared to prior and likely represent a combination of effusion and atelectasis , although left lower lobe pneumonia can not be excluded . Mild pulmonary edema appears slightly worse in the interval . No pneumothorax is detected on this view . Heart size is enlarged . The aorta is calcified . Median sternotomy wires and mediastinal clips likely reflect prior CABG .
