Trial summary

This study will investigate Ebstein's anomaly, a congenital abnormality of the tricuspid valve of the heart and try to identify the genetic origins of the disease. Adults and children 2 years of age and older with Ebstein's anomaly and healthy volunteers may be eligible for this study. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Who may be able to join

  • Patients who have diagnosed Ebstein's anomaly or tricuspid valve disease in Belarus or Ukraine and their parents will be asked to participate in this study regardless of sex, age, or race. In addition, sex and age matched neighborhood children and their parents will be recruited as controls. There is no known ethnic or racial predilection for Ebstein's anomaly or tricuspid valve disease.

Who cannot join

  • There are no exclusion criteria. This may allow us to discover previously unknown relationships between Ebstein's anomaly and other diseases.

About this study

Official title: Genes Causing Congenital Ebstein's Anomaly

This study will investigate Ebstein's anomaly, a congenital abnormality of the tricuspid valve of the heart and try to identify the genetic origins of the disease.

Adults and children 2 years of age and older with Ebstein's anomaly and healthy volunteers may be eligible for this study. Participants undergo the following procedures:

  • Blood tests: Three tube of blood will be collected, with the total amount limited to about half a teaspon for each two pounds of body weight.
  • Saliva sample collection: A small amount of saliva is collected by spitting into a sterile container.
  • Oral (cheek) swab: Cells are collected from the mouth using a soft brush to swab the inside lining of the cheek.
  • Electrocardiogram: The electrical activity of the heart is recorded using electrodes placed on the chest.
  • Echocardiogram: Heart function is assessed using ultrasound.
Read the detailed description

The goal of this study is to elucidate the genetic basis for the congenital heart disease (CHD) known as Ebstein's anomaly. These studies complement ongoing research studies using mouse models to recover mutations causing structural heart defects associated with human CHD. By elucidating the underlying genetic causes for Ebstien's anomaly, it may be possible to improve risk assessments as well as facilitate the development of new strategies for prevention and disease management. These studies are important for early diagnosis and the management of complications associated with surviving adults with Ebstein's anomaly, some of whom have undergone surgical correction and others that are unoperated.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Septal Defects, Ventricle and Heart Defects, Congenital, run by National Heart, Lung, and Blood Institute (NHLBI) at 3 sites in 3 countries.

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 1 inclusion and 1 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 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Belarus, Ukraine. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00497705, which also lists 3 linked publications.

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 2 Jul 2017.
