Figure 1 Fluoroscopic views in anteroposterior projection showing the NaviStar-RMT catheter incorporating a small permanent magnet in the tip and two other magnets in the distal portion of the device. The soft distal catheter body allows the tip to be deflected in any direction (A to C) and steered by the magnetic navigation system to reach the targeted right-superior pulmonary vein (D). Two standard quadripolar catheters are placed into the coronary sinus and right ventricle.
