About this study

The purpose of this clinical investigation is the continued assessment of the decision accuracy of St. Jude Medical (SJM) ICD with enhanced SVT discriminators in the treatment of subjects with primary and secondary prevention of sudden cardiac death.

Read the detailed description

With Ellipse™ and Fortify Assura™ ICD family, St. Jude Medical introduced enhanced device algorithms that may be helpful to further improve SVT discrimination success: SecureSense™, Far field morphology, Chamber Onset. These algorithms in combination with a tailored device setting (primary or secondary prevention) will be prospectively investigated within this trial.

What is being measured

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

  1. Inappropriate ICD shocks

    Freedom from inappropriate automatically delivered ICD-shocks within 12 months Follow-Up (FU) period after ICD/CRT-D implantation

    Measured: 12 months

Secondary outcomes (8)
  1. ICD shocks for any reason

    Freedom from automatically delivered ICD shocks for any reason during FU period

    Measured: 12 months

  2. Inappropriate ICD therapies

    Freedom from automatically delivered inappropriate ICD therapies during FU period

    Measured: 12 months

  3. Untreated VT/VF

    Freedom from untreated sustained ventricular tachycardia (VT) / ventricular fibrillation (VF) during FU period

    Measured: 12 months

  4. Accuracy of ICD therapy decision

    Accuracy of ICD therapy decision (VT/VF and nonVT/VF)

    Measured: 12 months

  5. Specificity

    Specificity for…

    • … other than sustained VT/VF
    • … SVT (Supraventricular tachycardia)
    • … different subtypes of SVTs (Sinus Tachycardia, Atrial Fibrillation, Atrial Flutter, other SVT).

    Measured: 12 months

  6. Cardiac deaths

    Cardiac deaths

    Measured: 12 months

  7. Sensitivity

    Sensitivity for sustained VT/VF

    Measured: 12 months

  8. ICD/CRT-D related SAE

    ICD/CRT-D related Serious Adverse Events (SAE)

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing ICD with enhanced SVT discriminators in people with Tachycardia, run by Abbott Medical Devices at 23 sites in 2 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 6 inclusion and 8 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 4 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in Germany, Estonia. 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?

Inappropriate ICD shocks (time frame: 12 months). 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 4 Feb 2019.
