The use of interactive non-selective saturation is shown during an atrial-septal puncture and septostomy experiment. The active guide-wire is color-highlighted in green and blended with background long-axis (A) and short-axis (B) views. The first column shows the device across the septum and coiled in the left atrium. Saturation is enabled in the second and third columns, with the Gd-filled balloon clearly visible in the third column.
