Device closing aortopulmonary window is seen on chest X-ray PA view in different styles. Upper left panel shows a standard PA view with device faintly seen to the left of the spine, medial to the upper left cardiac border. The upper left panel shows a darkened image of the X-ray which makes the device a little more prominent. The lower middle panel is a magnified view of the device, which clearly shows two discs of the device, with left disc being smaller than the right one. Shape of the device is suggestive of an Amplatzer device. It is easy to miss the device on the routine chest X-ray unless one is aware of the presence of the device. The radio opaque markers are barely visible. Close scrutiny near the markers makes the presence of the discs of the device more evident. On a film, it will be better seen if it is a penetrated view. With the availability of post processing on digital X-rays, it is easy to make the device appear more prominent as we have done here. The device will be much better seen on cine X-ray fluoroscopy.
