Trial summary

Ebstein anomaly is a rare congenital heart disease. It encompasses abnormalities of the tricuspid valve, the right atrium and the right ventricle (RV). Currently, cardiac magnetic resonance imaging (MRI) is considered the method of choice for the assessment of RV volume and function. Read more about this study

About this study

Official title: Left Ventricular Function in Ebstein Anomaly: Assessment by 3D Echocardiography and Speckle Tracking. Assessment and Validation of the Right Ventricle by VentriPoint Method.

Ebstein anomaly is a rare congenital heart disease. It encompasses abnormalities of the tricuspid valve, the right atrium and the right ventricle (RV).

Currently, cardiac magnetic resonance imaging (MRI) is considered the method of choice for the assessment of RV volume and function. To evaluate the right heart function VentriPoint method was designed to assess the RV in a fraction of the time, resulting in better efficacy and lower costs. VentriPoint is approved for Tetralogy of Fallot patients as well as patients with systemic RV in d-transposition of the great arteries. This method uses 2 dimensional standard ultrasound views linked to a VentriPoint Medical Systems unit. After acquisition, the physician identifies anatomical landmarks with dots on a number of the 2D ultrasound views through the heart. With a sensor (magnetic tracking system: GPS) on the ultrasound probe we know where the 2D plane is in 3D space. In this way the precise anatomical landmark is located in 3D space.

The aim of the present study is to assess the feasibility, reliability and accuracy of the echocardiographic knowledge-based 3D reconstruction method to measure RV volume and function in patients with Ebstein anomaly. The accuracy of the method will be assessed by comparison with measurements obtained by cardiac MRI.

In addition to the right ventricle the investigators want to assess the left ventricular function in patients with Ebstein anomaly in this study. By using speckle tracking echocardiography the investigators would like to investigate on the left ventricular contractility, rotation and synchrony of the left ventricle together with the RV. Not seldom the left ventricle is neglected in a patient with Ebstein anomaly by impressive findings of the right ventricle. Changes in the myocardial left ventricular structure (non compaction) are also described and may have negative impact on the function.

The investigators want to analyze 25-30 patients with Ebstein anomaly including children starting at 11 years of age.

What is being measured

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

  1. Right ventricular volume (ml/m2) and function by VentriPoint. Structural myocardial changes in the left ventricle (Strain).

    Comparison of the VentriPoint findings with measurements obtained by cardiac MRI.

    Structural changes of the left ventricle by echocardiography as well as ventricular longitudinal deformation in strain value by speckle tracking echocardiography.

    Measured: 1 year

Secondary outcomes (1)
  1. Correlation of findings with clinical symptoms

    Correlation with the severity of tricuspid regurgitation, the clinical symptoms, size and function of the right ventricle

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Ebstein Anomaly, run by Angela Oxenius at 1 site in Switzerland.

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 4 inclusion and 4 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 27 May 2015. 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 Switzerland. 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?

Right ventricular volume (ml/m2) and function by VentriPoint. Structural myocardial changes in the left ventricle (Strain). (time frame: 1 year). 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 27 May 2015; AzTrials last refreshed its copy on 6 Nov 2026.
