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

November 23, 2017 updated by: Anne-Marie Noten, Erasmus Medical Center

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

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Description

Inclusion Criteria:

  • patients with a clinical indication for RF ablation of cardiac arrhythmias with the Niobe Remote Magnetic Navigation system
  • patients referred to one of the participating ablation centers
  • written informed consent

Exclusion Criteria:

  • presence of a atrial thrombus or left atrial appendage (LAA) thrombus seen on (contrast) echocardiography or MRI

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients with cardiac arrhythmias undergoing RF ablation
Patients with cardiac arrhythmias will be undergoing RF ablation using the Niobe Remote Magnetic Navigation System with CDS as their standard of care. System performance data will only be collected during the RF ablation procedure. Outcome measures will be evaluated with the CDS connected and without the CDS connected within all patients.
Device: CDS box connection of the Niobe™ Remote Magnetic Navigation System
For all subjects included in the study, the ablation procedure will be started per standard of care. First mapping, pacing and electrocardiograms of the right atrium will be evaluated without the CDS box connected. Second the CDS box will be connected to the catheter and mapping, pacing and electrocardiograms will be recorded again. Next, ablation will be conducted per standard of care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mapping quality
Time Frame: 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
One day - during ablation procedure
Pacing thresholds
Time Frame: 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
One day - during ablation procedure
Pacing capture
Time Frame: 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
One day - during ablation procedure
Electrocardiograms
Time Frame: 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
10 months - ECGs will be evaluated after inclusion is completed

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of procedure related major adverse events, attributed to the CDS system
Time Frame: 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
30 days
Number of procedure related minor adverse events, attributed to the CDS system
Time Frame: 30 days
Minor adverse events: post procedural precordial pain, phrenic nerve injury, minor bleeding - type II
30 days
Number of acute procedure succes
Time Frame: 1 day - during ablation procedure
Number of procedures with successful electrical isolation of ablated area
1 day - during ablation procedure

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
