About this study

Sudden cardiac death is a frequent cause of cardiovascular mortality. Numerous rhythmic risk assessment criterion have been described targeting the substratum, the cardiac nervous tone or the trigger of arrhythmias. Development of ventricular tachycardia ablation in the past few years show interesting results preventing the recurrence of ventricular arrhythmias.

Sudden cardiac death is a frequent cause of cardiovascular mortality. Numerous rhythmic risk assessment criterion have been described targeting the substratum, the cardiac nervous tone or the trigger of arrhythmias. Development of ventricular tachycardia ablation in the past few years show interesting results preventing the recurrence of ventricular arrhythmias.

Rhythmic risk assessment criterions have never been studied in relation with ventricular tachycardia ablation. The purpose of this study is to explore the modifications of these criterions after ventricular tachycardia ablation.

What participants receive

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

  • ventricular tachycardia ablationProcedure or surgery

    The usual organization of hospitalization of the patients addressed for ventricular tachycardia ablation and his follow-up are not modified by the protocol. .

What is being measured

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

  1. measure assessing change before and after Ventricular Tachycardia Ablation of the non-invasive parameters analysis of the rhythmic risk before and after Ventricular Tachycardia Ablation

    non invasive parameters analysis of the rhythmic risk will be evaluated by the evaluation of the T wave alternans

    Measured: 10 minutes and 60 minutes after the Ventricular Tachycardia Ablation

Secondary outcomes (2)
  1. Assessing the correlations of the modifications of the risk criterion after ablation with the recurrences of arrhythmias at one year follow-up

    the recurrences of arrhythmias will be evaluated . There will be assessed by the informations reveled by the Implantable automatic defibrillator

    Measured: 3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation

  2. Study of the correlation between the modifications of non-invasive parameters analysis of the rhythmic risk and the success of the ablation procedure

    Success of the ablation procedure is defined by the absence of inducible Ventricular Tachycardia at the end of the procedure.

    Measured: 3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation

Questions about this trial

What is this clinical trial studying?

An observational study of Ventricular Tachycardia, run by University Hospital, Toulouse 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 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: status not confirmed, as of the sponsor's last update on 11 Jul 2018. 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?

Results are not available in the source record.

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

Contact Philippe MAURY, MD (05 61 32 31 00, maury.p@chu-toulouse.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

measure assessing change before and after Ventricular Tachycardia Ablation of the non-invasive parameters analysis of the rhythmic risk before and after Ventricular Tachycardia Ablation (time frame: 10 minutes and 60 minutes after the Ventricular Tachycardia Ablation). 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 11 Jul 2018.
