About this study

This study will evaluate the feasibility of visualization and characterization of arrhythmia ablation lesions by MRI immediately following standard ablation techniques. The appearance of the ablation lesion will be correlated with clinical outcomes and risk of arrhythmia recurrence.

Read the detailed description

Children's National Heart Institute (CNHI) with major contractual support from the National Institutes of Health / National Heart, Lung and Blood Institute has installed a combined X-ray / Magnetic Resonance Imaging cardiac catheterization lab suite allowing for experts in the fields of cardiac MRI, interventional cardiac MRI and clinical pediatric interventional electrophysiology to work together to make substantial advancements in the development of novel techniques and applications to reach the goal of improved survival and care for the congenital heart disease population. The CNHI X-ray/MRI suite will allow for streamlined transfer of patients from fluoroscopy directly to the MRI scanner under the same sedation thereby allowing for immediate post procedure imaging and minimizing risk to the patient.

    Measured: Post ablation up to 5 years

Secondary outcomes (2)
  1. To measure the size of the ablation lesion on cardiac MR imaging

    Measured: At the end of each ablation procedure through study completion, up to 5 years.

  2. The number of post ablation MR images with a visible lesion.

    Measured: At the end of each ablation procedure through study completion, up to 5 years.

Questions about this trial

What is this clinical trial studying?

A study testing MRI scan in people with Ventricular Tachycardia and Cardiac Arrhythmia, run by Children's National Research Institute at 1 site in United States.

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 2 inclusion and 11 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 21 Jan 2020. 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 United States. 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?

The number of participants following ablation procedure who: a). have an arrythmia reoccurrence, b). require a repeat ablation procedure, and c). require treatment for arrhythmia management (time frame: Post ablation up to 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02761343, which also lists 40 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 21 Jan 2020.
