A Magnetic-Resonance-Imaging-Compatible Remote Catheter Navigation System [PDF]

IEEE Transactions on Biomedical Engineering, 2013
A remote catheter navigation system compatible with magnetic resonance imaging (MRI) has been developed to facilitate MRI-guided catheterization procedures. The interventionalist's conventional motions (axial motion and rotation) on an input catheter - acting as the master - are measured by a pair of optical encoders, and a custom embedded system ...

Comparison of atrial fibrillation ablation efficacy using remote magnetic navigation vs. manual navigation with contact-force control

Biomedical Papers, 2020
Aims: This study aims to compare procedural parameters and clinical efficacy of remote magnetic navigation (RMN) vs. manual navigation (MAN) approach for radiofrequency ablation (RFA) in patients with atrial fibrillation (AF).

Statistical Characterization of the Magnetic Field in Space during Magnetic Storms

Atmosphere, 2022
Magnetic storms are an important type of space weather and are usually caused by large streams of charged elementary particles (ions, for example) generated during solar wind production. The occurrence of magnetic storms can pose a threat to the internal

Remote Magnetic Navigation: A Focus on Catheter Ablation of Ventricular Arrhythmias [PDF]

Journal of Cardiovascular Electrophysiology, 2016
A Focus on Catheter Ablation of Ventricular ArrhythmiasVT ablation is based on percutaneous catheter insertion under fluoroscopic guidance to selectively destroy (i.e., ablate) myocardial tissue regions responsible for the initiation or propagation of ventricular arrhythmias.

Feasibility and outcome of supraventricular tachycardia ablation via a retrograde access using remote magnetic navigation in patients with physiologically univentricular hearts after Damus-Kaye-Stansel surgery

International Journal of Cardiology Congenital Heart Disease, 2021
Aims: Supraventricular tachycardia (SVT) is one of the most frequent complications in adult patients with congenital heart disease (CHD). Limited experience exists for successful ablation in complex CHD patients with prior Damus-Kaye-Stansel (DKS ...

Remote magnetic navigation and arrhythmia ablation

Archives of Cardiovascular Diseases, 2012
Radiofrequency treatment is the first-choice treatment for arrhythmias, in particular complex arrhythmias and especially atrial fibrillation, due to the greater benefit/risk ratio compared with antiarrhythmic drugs. However, complex arrhythmias such as atrial fibrillation require long procedures with additional risks such as X-ray exposure or serious ...

Remote magnetic navigation for treatment of patients with atrial fibrillation

Patologiya krovoobrashcheniya i kardiokhirurgiya, 2022
Atrial fibrillation (AF) remains an important medical and social health problem occupying a leading position among all cardiac arrhythmias in clinical practice. AF increases overall mortality by 1.9 times and the risk of stroke by 5 times, leads to disability among the working-age population, and reduces the quality of life.

Initial Experience With Remote Catheter Ablation Using a Novel Magnetic Navigation System [PDF]

Circulation, 2004
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—
