About this study

The study is designed to collect data of the performance and confirm the safety of the DX (Diagnostic eXtension) functionality in the Lumax 640/470 HF-T in patients with permanent atrial fibrillation and CRT-D indication according to current ESC guidelines. The DX functionality is a feature, which can be activated in the Lumax 640/740 HF-T when connected to the LinoxSMART S DX right ventricular lead. The combination of these devices enable atrial sensing via a sensing dipole in the ventricular lead and therefore reduces the number of implanted leads without sacrificing atrial information. Atrial pacing can not be provided but is not needed in patients with permanent atrial fibrillation.

What is being measured

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

  1. Quality of IEGM recording

    to assess if the IEGM Online recordings of the Lumax 640/740 HF-T with DX functionality provide adequate quality to classify the atrial rhythm

    Measured: 3 months

  2. Safety of the Lumax 640/740 HF-T with DX functionality based on the Serious Adverse Device Effects related to the DX functionality

    to assess the safety of the Lumax 640/740 HF-T by the analysis of Serious Adverse Device Effects which are related to the DX functionality

    Measured: 3 months

  3. Safety of the Lumax 640/740 HF-T with DX functionality based on all, serious and non-serious, Adverse Device Effects related to DX functionality

    to assess the safety of the Lumax 640/740 HF-T with DX functionality by the analysis of all (serious and non-serious) Adverse Device Effects which are related to the DX functionality

    Measured: 3 months

  4. Number of patients with maintenance of diagnosis of permanent AF

    to investigate whether the diagnosis of permanent AF at enrollment is maintained after device implantation

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation and Heart Failure, run by Biotronik SE & Co. KG at 5 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 7 inclusion and 7 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 11 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Germany, 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?

Quality of IEGM recording (time frame: 3 months). The study lists 4 primary outcomes in all. 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 NCT01930695, which also lists 1 linked publication.

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 Apr 2018.
