“…The general principles of the MediGuide system have been previously described . In brief, the MediGuide system consists of three components: a transmitter generating a 3D electromagnetic field, an electromagnetic field reference sensor attached to the patient's chest, and a miniaturized single‐coil sensor assembled within the diagnostic or ablation catheter.…”

“…While the use of nonfluoroscopic three‐dimensional (3D) navigation systems during catheter ablation procedures has resulted in a significant reduction in fluoroscopy, the lack of complete integration means that the use of fluoroscopy remains necessary during electrophysiological studies and ablation procedures . A recently developed nonfluoroscopic sensor‐guided electromagnetic navigation system (MediGuide™, St. Jude Medical Inc., St. Paul, MN, USA), which applies real‐time 3D visualization to previously recorded fluoroscopic images and carries the potential to reduce ionizing radiation exposure during electrophysiological procedures . This tracking system uses electromagnetic signals to localize the MediGuide‐enabled catheters relative to a source of known position.…”

“…Case reports and single‐cohort studies revealed feasibility of this system during invasive electrophysiology studies, and catheter ablation procedures for supraventricular tachycardia, atrial flutter (AFL), and atrial fibrillation (AF) . In these studies, a significant reduction of fluoroscopy time and exposure was observed when procedures were performed with the MediGuide system compared to conventional ablation procedures.…”

“…To date, four 3-D mapping systems (Table 1) Pre-acquired ecg and respiration triggered biplane short sequences of conventional fluoroscopic frames allow traditional catheter and structure visualisation tracking within dynamic, virtual cardiac chamber models (4D model). The system is based on a dynamic electromagnetic field integrated with a miniaturized single coil sensor mounted on dedicated electrophysiology catheters and a reference sensor attached to the patient's chest 15 . In fact, given these features, Mediguide technology, is not only dedicated to arrhythmia ablation procedures but is also useful in other procedures requiring long fluoroscopy time exposure, as cardiac resynchronization implantation 16 .…”

Abstract:While radiation exposure related to natural sources plays a minor role, medicine-related exposure, represents, to date, a major exposure source. Within this exposure interventional electrophysiology is a relevant contributor. Unfortunately no safe dose in radioprotection exists, the negative acute and long term effects of radiological exposure may emerge at any radiation exposure dose. For this reason patients and physicians should be aware of the risk of radiation exposure and the benefits of the imaging/procedure balanced by the required radiation exposure. Given this, performing a near to zero x-rays transcatheter ablation procedure should therefore represent an aim for all electrophysiological lab. Fortunately, the introduction of electroanatomic mapping systems, have provided the possibility to perform simple and complex electrophysiological procedures avoiding, or at least, limiting the use of radiations. The present review summarizes state of the art of feasibility and safety of the near to zero approach for the main electrophysiological procedures, highlighting the potential health benefits.3

Background-Cardiac resynchronization therapy (CRT) device implantation can be challenging, time consuming, and fluoroscopy intense. To facilitate left ventricular lead placement, a novel sensor-based electromagnetic tracking system (MediGuide Technology [MGT], St. Jude Medical) has been developed. We report the results of the First Human Use study evaluating the feasibility, safety, and performance of a novel CRT implantation approach using electromagnetic trackable operation equipment. Methods and Results-Fifteen consecutive patients (66±8 years, 53% male) with an established indication for CRT were implanted using the new tracking technology. Demographics, anatomical information, detailed fluoroscopy need, procedure time, and adverse events were collected. Patients were followed up for 4 weeks after implantation. The CRT system was successfully implanted with a lateral or posterolateral left ventricular lead position in all patients. The total procedure time was 116±43 minutes, the median total fluoroscopy time (skin to skin) was 5.2 (Q1-Q3, 3.0-8.4) minutes, and the median fluoroscopy time for left ventricular lead deployment (coronary sinus [CS] cannulation to withdrawal of CS sheath) measured 2.6 (Q1-Q3, 1.6-5.6) minutes. There were no severe complications that required an acute intervention or reoperation during the perioperative and postoperative periods. Conclusions-Use of the MGT tracking technology allows for safe and successful CRT implantation with the potential for reduced fluoroscopy time. Future randomized studies are needed to validate these data. Clinical Trial Registration-URL http://www.clinicaltrials.gov.
