EchoNavigator^® during atrial septal defect closure. A: Shows in the Echo-view in the right upper panel an X-plane view of the interatrial septum with a bicaval and a short axis view. The defect is clearly illustrated and marked with a red circle, appearing also in the X-ray-view as the target lesion; B: Demonstrates the occluder device after deployment of both the left and the right atrial disc. Note in the right upper panel that the two discs embrace the red target marker, where the defect was previously located.
