Cavo-tricuspid isthmus radiofrequency ablation using a novel remote navigation catheter system in patients with typical atrial flutter.
AIMS A new remote catheter system (AMIGO™ Remote Catheter System) compatible with conventional ablation catheters is now commercially available but no data about its performance in clinical use during ablation have been reported. This study evaluates the feasibility, efficacy, and safety of cavo-tricuspid isthmus (CTI) ablation with this system in patients with typical atrial flutter (AFl). M...
متن کاملElectroanatomic mapping and radiofrequency ablation of porcine left atria and atrioventricular nodes using magnetic resonance catheter tracking.
BACKGROUND The MRI-compatible electrophysiology system previously used for MR-guided left ventricular electroanatomic mapping was enhanced with improved MR tracking, an MR-compatible radiofrequency ablation system and higher-resolution imaging sequences to enable mapping, ablation, and ablation monitoring in smaller cardiac structures. MR-tracked navigation was performed to the left atrium (LA)...
متن کاملCombined 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...
متن کاملCathROB: A Highly Compact and Versatile Remote Catheter Navigation System
Several remote catheter navigation systems have been developed and are now commercially available. However, these systems typically require specialized catheters or equipment, as well as time-consuming operations for the system set-up. In this paper, we present CathROB, a highly compact and versatile robotic system for remote navigation of standard tip-steerable electrophysiology (EP) catheters...
متن کاملEndovascular catheter for magnetic navigation under MR imaging guidance: evaluation of safety in vivo at 1.5T.
BACKGROUND AND PURPOSE Endovascular navigation under MR imaging guidance can be facilitated by a catheter with steerable microcoils on the tip. Not only do microcoils create visible artifacts allowing catheter tracking, but also they create a small magnetic moment permitting remote-controlled catheter tip deflection. A side product of catheter tip electrical currents, however, is the heat that ...
