Prospective Physician-Initiated Observational Study of The Contact Detection System (CDS) in Patients Undergoing Radiofrequency Ablation Using the Niobe™ Remote Magnetic Navigation System

Completed

• Conditions: Atrial Fibrillation; Catheter Ablation

• Registration Number: NCT03103945
• Lead Sponsor: Erasmus Medical Center

Brief Summary

This observational study evaluates peri-procedural results of the Niobe™ Remote Magnetic Navigation (RMN) ES system using the contact detection system (CDS) in patients undergoing standard of care radiofrequency ablation of cardiac arrhythmias.

The objective of this observational study is to confirm system performance of the CDS and that it does not alter pacing, electrocardiograms, or mapping during RF ablation procedures.

Primary Outcome Measures

Name	Time	Method
Pacing thresholds	One day - during ablation procedure	Pacing thresholds of three separate areas of the right atrium without CDS box connected and pacing thresholds of the same three areas with CDS box connected
Pacing capture	One day - during ablation procedure	Pacing capture of three separate areas of the right atrium without CDS box connected and pacing capture of the same three areas with CDS box connected
Electrocardiograms	10 months - ECGs will be evaluated after inclusion is completed	Difference between and disturbance of the intracardiac electrocardiograms without the CDS box connected versus with the CDS box connected, evaluated by two independent and blinded electrophysiologists
Mapping quality	One day - during ablation procedure	Physician's and technician's subjective score of the quality of mapping the right atrium without CDS box connected and with CDS box connected

Secondary Outcome Measures

Name	Time	Method
Number of procedure related major adverse events, attributed to the CDS system	30 days	Major adverse events: death, acute myocardial infarction (AMI) or coronary artery damage, major bleeding - type III and V, abdominal bleeding, tamponade \> 80cm3, late tamponade, ischemic cerebral event
Number of procedure related minor adverse events, attributed to the CDS system	30 days	Minor adverse events: post procedural precordial pain, phrenic nerve injury, minor bleeding - type II
Number of acute procedure succes	1 day - during ablation procedure	Number of procedures with successful electrical isolation of ablated area
