Sensor‐Based Electromagnetic Navigation (Mediguide®): How Accurate Is It? A Phantom Model Study

Abstract

The MediGuide® system shows a very high level of accuracy regarding localization reproducibility as well as spatial and visual accuracy, which can be ascribed to the magnetic field localization technology. The observed offsets between the geometry visualization and the real phantom are below a clinically relevant threshold.

Reducing Radiation Exposure During CRT Implant Procedures: Single‐Center Experience With Low‐Dose Fluoroscopy Settings and a Sensor‐Based Navigation System (MediGuide)

“…As of January 2015, software updates rendered it possible to adopt lower‐dose fluoroscopy settings (i.e., 3 instead of 6 fps and 23 instead of 40 nGy/pulse, both with an 8.0‐millisecond pulse duration), which were systematically adopted in all 3 EP labs and applied to all patients. Details about the MDG technology, its interface, potential applications, and the technique for CRT implantation have been previously described . In brief, the system consists of 3 components: a transmitter that generates a 3D electromagnetic field, an electromagnetic reference patch positioned on the patient's chest, and a miniaturized sensor incorporated within the LV‐related implant tool (e.g., guiding sheath, sub‐selection catheter, decapolar CS catheter, and 0.014" guide‐wire).…”

Development of a patient‐specific atrial phantom model for planning and training of inter‐atrial interventions

“…The heartbeat is simulated through water or air pumps, with functional parameters similar to the physiological ones. Recently, some authors focused on atrial phantom models . These models were mainly used for training/planning of cardiac ablations, presenting the atrial body and the proximal part of the pulmonary veins.…”

“…Recently, some authors focused on atrial phantom models. 11,18,19 These models were mainly used for training/planning of cardiac ablations, 19,20 presenting the atrial body and the proximal part of the pulmonary veins. Nevertheless, these solutions were either rigid 19 or not appropriate for ultrasound (US) acquisition.…”

Initial experience of a novel mapping system combined with remote magnetic navigation in the catheter ablation of atrial fibrillation

“…It is influenced by impedance changes and differences in tissue types. Studies demonstrated that electromagnetic catheter localization offers a higher level of accuracy as it operates independently from tissue properties compared to impedance measurement‐based electric catheter localization . Recently, the next‐generation novel mapping system, EnSite Precision mapping system (St. Jude Medical, Inc.) was introduced, which combines both impedance and magnetic technologies.…”
