Remote Magnetic Navigation

Initial experience with remote catheter ablation using a novel magnetic navigation system: magnetic remote catheter ablation.

BACKGROUND Catheters are typically stiff and incorporate a pull-wire mechanism to allow tip deflection. While standing at the patient's side, the operator manually navigates the catheter in the heart using fluoroscopic guidance. METHODS AND RESULTS A total of 42 patients (32 female; mean age, 55+/-15 years) underwent ablation of common-type (slow/fast) or uncommon-type (slow/slow) atrioventri...

Remote magnetic catheter navigation for cavotricuspid isthmus ablation in patients with common-type atrial flutter Vollmann: Remote magnetic isthmus ablation

Remote magnetic catheter navigation: more than just bells and whistles ?

Catheter ablation is nowadays an established treatment modality for both atrial and ventricular tachyarrhythmias. Manual navigation of the ablation catheter can be challenging in patients with a complex cardiac anatomy due to, for example, (surgically corrected or palliated) congenital heart defects, resulting in a long procedure time and excessive X-ray exposure. In the past decades, sophistic...

Combined remote magnetic navigation and ultra-high-density mapping (Rhythmia™) in slow pathway ablation.

A new ultra-high-density mapping system (RhythmiaTM) is gaining increasing interest from the electrophyology community, especially for the mapping of organized complex tachycardias. The system uses the magnetic tracking of the mapping catheter. Whether this system is compatible with magnetic navigation is not known. We report the first case of combined ultra-high-density mapping and remote magn...

Comparison of remote magnetic versus manual catheter navigation for ablation of atrioventricular nodal reentry tachycardia

Objective The purpose of this study was to compare remote magnetic catheter navigation with manual navigation for the ablation of atrioventricular nodal reentry tachycardia (AVNRT). Methods From November 2007 to November 2009, 30 consecutive patients with AVNRT received radiofrequency ablation in the Institute of Geriatric Cardiology. Of them, 14 were treated with remote magnetic navigation (RM...

Remote Magnetic Navigation for Accurate, Real-time Catheter Positioning and Ablation in Cardiac Electrophysiology Procedures

New remote navigation systems have been developed to improve current limitations of conventional manually guided catheter ablation in complex cardiac substrates such as left atrial flutter. This protocol describes all the clinical and invasive interventional steps performed during a human electrophysiological study and ablation to assess the accuracy, safety and real-time navigation of the Cath...
