Abstract Introduction : The Stereotaxis Niobe® magnetic navigation system (MNS; Stereotaxis, St. Louis, MO) facilitates precise vector based of magnetically‐enabled guidewires for percutaneous coronary intervention (PCI) by using two permanent magnets located on opposite sides the patient table to produce a controllable field. objective this study is describe results large series system, compare with historical control group, and detail MNS learning curve. Methods We prospectively collected data 439 lesions in 350 consecutive PCI patients predominantly radial approach. All were entered into customized database capture key parameters then compared previously stent registry from same center. Results In 410/439 (93%) wire crossed lesion successfully MNS. Twenty‐five 35 failures chronic total occlusions. No perforations or dissections occurred population. Lesion crossing time was 81 ± 168 sec (mean SD), fluoroscopy 64 123 sec. A clear curve evident after first 80 patients. Contrast use reduced when group. Procedural times similar. Conclusions Use may enable successful performance more complex procedures cardiac catheterization laboratory an improvement efficiency. © 2008 Wiley‐Liss, Inc.
