Figure 1. Typical postoperative cardiac surgery chest radiograph. First postoperative study for a 58-year-old radiologist (!) who underwent coronary artery bypass graft (CABG) surgery. The image is underexposed and shows a confusing array of apparatus, including overlying oxygen tubing, a pulmonary artery catheter, a nasogastric tube, an endotracheal tube, a mediastinal drain, median sternotomy wires, mediastinal clips, electrocardiographic (ECG) leads, and incipient left lower lobe atelectasis and pleural fluid.
