Robotic magnetic navigation (RMN) (also called remote magnetic navigation) uses robotic technology to direct magnetic fields which control the movement of magnetic-tipped endovascular catheters into and through the chambers of the heart during cardiac catheterization procedures.{{cite journal |last1=Da Costa |first1=A |last2=Guichard |first2=JB |last3=Roméyer-Bouchard |first3=C |last4=Gerbay |first4=A |last5=Isaaz |first5=K |title=Robotic magnetic navigation for ablation of human arrhythmias |journal= Medical Devices: Evidence and Research|date=2016 |volume=9 |pages=331–339 |doi=10.2147/MDER.S96167 |pmid=27698569|pmc=5034914 |doi-access=free }}
Devices
Because the human heart beats during ablation procedures, catheter stability can be affected by navigation technique. Magnetic fields created by RMN technology guide the tip of a catheter using a “pull” mechanism of action (as opposed to “push” with manual catheter navigation). Magnetic catheter navigation has been associated with greater catheter stability.{{cite journal |last1=Davis |first1=DR |last2=Tang |first2=AS |last3=Gollob |first3=MH |last4=Lemery |first4=R |last5=Green |first5=MS |last6=Birnie |first6=DH |title=Remote magnetic navigation-assisted catheter ablation enhances catheter stability and ablation success with lower catheter temperatures |journal=Pacing and Clinical Electrophysiology |date=July 2008 |volume=31 |issue=7 |pages=893–8 |doi=10.1111/j.1540-8159.2008.01105.x |pmid=18684288|s2cid=19617848 }}
Medical use
=Atrial fibrilation=
As of 2015 there were two robotic catheterization systems on the market for atrial fibrilation; one of them used magnetic guidance.{{cite journal |last1=Gerstenfeld |first1=EP |last2=Duggirala |first2=S |title=Atrial fibrillation ablation: indications, emerging techniques, and follow-up |journal=Progress in Cardiovascular Diseases |date=2015 |volume=58 |issue=2 |pages=202–12 |doi=10.1016/j.pcad.2015.07.008 |pmid=26241304}}
After long-term follow up, RMN navigation has been associated with better procedural and clinical outcomes for AF ablation when compared with manual catheter navigation for cardiac ablation.{{cite journal |last1=Yuan |first1=S |last2=Holmqvist |first2=F |last3=Kongstad |first3=O |last4=Jensen |first4=SM |last5=Wang |first5=L |last6=Ljungström |first6=E |last7=Hertervig |first7=E |last8=Borgquist |first8=R |title=Long-term outcomes of the current remote magnetic catheter navigation technique for ablation of atrial fibrillation |journal=Scandinavian Cardiovascular Journal |date=December 2017 |volume=51 |issue=6 |pages=308–315 |doi=10.1080/14017431.2017.1384566 |pmid=28958165|s2cid=25501499 }}
=Ventricular tachycardia=
RMN has been shown to be safe and effective for cardiac catheter ablation in various patient populations with ventricular tachycardia.{{cite journal |last1=Turagam |first1=MK |last2=Atkins |first2=D |last3=Tung |first3=R |last4=Mansour |first4=M |last5=Ruskin |first5=J |last6=Cheng |first6=J |last7=Di Biase |first7=L |last8=Natale |first8=A |last9=Lakkireddy |first9=D |title=A meta-analysis of manual versus remote magnetic navigation for ventricular tachycardia ablation |journal=Journal of Interventional Cardiac Electrophysiology |date=September 2017 |volume=49 |issue=3 |pages=227–235 |doi=10.1007/s10840-017-0257-3 |pmid=28624892|s2cid=21925778 }}{{cite journal |last1=Akca |first1=F |last2=Önsesveren |first2=I |last3=Jordaens |first3=L |last4=Szili-Torok |first4=T |title=Safety and efficacy of the remote magnetic navigation for ablation of ventricular tachycardias--a systematic review |journal=Journal of Interventional Cardiac Electrophysiology |date=June 2012 |volume=34 |issue=1 |pages=65–71 |doi=10.1007/s10840-011-9645-2 |pmid=22180126|pmc=3342497 }}
