Trial summary

Hypertrophic cardiomyopathy (HCM) is very common. The thickened heart muscle can disrupt the normal functioning of the heart's electrical system, resulting in fast or irregular heartbeats. Today, there are no reliable means to identify HCM patients at risk of sudden death. Read more about this study

About this study

Official title: 3D Non-invasive Myocardial Electrical Propagation Mapping as a New Tool to Predict Sudden Death Risk in Patients With Hypertrophic Cardiomyopathy: A Pilot Study

Hypertrophic cardiomyopathy (HCM) is very common. The thickened heart muscle can disrupt the normal functioning of the heart's electrical system, resulting in fast or irregular heartbeats. Today, there are no reliable means to identify HCM patients at risk of sudden death. The CardioInsight™ has recently been developed by Medtronic for non-invasive advanced cardiac mapping system. The CardioInsight™ Noninvasive 3D Mapping System is a non-invasive mapping system that collects chest ECG signals and combines these signals with CT scan data to produce and display simultaneous, bi-atrial and biventricular, 3-D cardiac maps.

It is a monocentric, prospective, comparative and analytical study. 20 HCM patients will be recruited in the National Reference Center for inherited cardiac diseases of Lyon. The 3D-propagation maps of 10 well phenotyped and genotyped HCM patients with previous VF (ventricular fibrillation) will be compared to 10 HCM patients without previous VF.

After consent signed, Holter ECG, scanner and CardioInsightTM 3D_ECG mapping will be planned in the month following the inclusion. 12-lead ECG, 24h holter ECG, cardiac scanner will be performed as standard procedure of each center in the current health care of the patient.

The widespread screening of HCM patients with 3D high-density noninvasive mapping should improve the risk-benefit ratio of implantable defibrillator therapy. It is expected that more patients at risk will benefit from this device.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CardioInsight™ Noninvasive 3D Mapping SystemDevice

    The CardioInsight system uses a proprietary, single-use, disposable multi-electrode vest to capture electrical signals from the body surface. The CardioInsight software provides various cardiac signal analyses and displays interactive 3-D color maps including activation, voltage, composite and phase maps. The vest wearing is coupled with a CT scan.

    This exam will be performed only at baseline visit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Identification of specific markers of risk of sudden death in HCM patients from the maps created by the combination of CT and signal data.

    The CardioInsight system uses a proprietary, single-use, disposable multi-electrode vest to capture electrical signals from the body surface. The CardioInsight software provides various cardiac signal analyses and displays interactive 3-D color maps including activation, voltage, composite and phase maps. The use of the CardioInsight system is correlated with a CT scan.

    Measured: Month 1

Questions about this trial

What is this clinical trial studying?

A study testing CardioInsight™ Noninvasive 3D Mapping System in people with Hypertrophic Cardiomyopathy, run by Hospices Civils de Lyon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identification of specific markers of risk of sudden death in HCM patients from the maps created by the combination of CT and signal data. (time frame: Month 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jan 2023.
