What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled This study
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study was designed to compare electrical and mechanical activation of the right ventricle in adults who had surgery for Tetralogy of Fallot, a congenital heart condition. Researchers planned to use 3D mapping and imaging to see if electrical signals match the heart's physical movement. However, the study was withdrawn before enrolling any participants, so no results are available.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Expected to start

Sep 2022

An estimate. Start dates often move.

Expected to finish

Sep 2024

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Inclusion Criteria in the Fallot group * Male or female patient aged 18, * Patient with Fallot Tetralogy operated. nclusion Criteria in the Control group * Male or female patient aged 18, * Patient benefiting from electrophysiological exploration for a healthy heart arrhythmia, * Patient with a significant lack of heart disease. Exclusion Criteria: Exclusion Criteria in the Fallot group * Patient with associated left heart disease, * Patient with an acoustic window that does not allow for proper echocardiography, * Patient with contraindication to MRI, * Woman of childbearing age without effective contraception (HAS criteria) or Pregnant (ßHCG \> 20 IU/l) or nursing woman. Exclusion Criteria in the Control group * Patient with an acoustic window that does not allow proper echocardiography, * Patient with MRI contraindication, * Woman of childbearing age without effective contraception (HAS criteria) or Pregnant (ßHCG \> 20 IU/l) or nursing woman, * Cardiac pathology detected during echocardiography.
