The initial chest X-ray after implantation showed right lower lobe anterior pneumothorax and pneumopericardium (Figure 1).

A computerized tomography (CT) scan of the chest was done to investigate the etiology of the contralateral pneumothorax that revealed right atrial lead projecting through the right atrial wall and right ventricular lead at the wall (Figure 2). Small amount of air was also visualized anterior and posterior to aorta likely mild pneumomediastinum (Figures 2-4).
