About this study

LV pacing at various sites with recording of ECG and subsequent signal analysis at different sites.

Read the detailed description

During routine cardiac resynchronization pacemaker or implantable defibrillator (ICD) implantation (including de-novo and upgrade from standard device, additional pacing within 3 different coronary veins will be performed in combination with a previously implanted right ventricular pacing or ICD lead. The resulting electrocardiogram signal will be analyzed afterwards. A time-frequency analysis (TFA) of several ECG leads at each paced site will be performed and compared. The results of the TFA analysis will not be used to select pacing lead location in this study.

The patient will then receive the left ventricular pacing lead in the standard manner.

What participants receive

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

  • Biotronik Vision GuidewireDevice

    The apical, mid ventricular and basal sites within the anterior,posterior and lateral coronary sinus branch veins will be paced.

Study groups in NCT03253809
Study groupRoleWhat they receive
Coronary Sinus Branch PacingExperimentalAfter cannulation, pacing impulses will be delivered via a Biotronik Vision Guidewire to 3 sites (apical, mid ventricular, and basal) within each coronary sinus branch receiving venous blood from the anterior, lateral and posterior regions of the ventricle. ECG signals will be saved digitally for analysis
Receives: Device: Biotronik Vision Guidewire

What is being measured

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

Questions about this trial

What is this clinical trial studying?

A study testing Biotronik Vision Guidewire in people with Cardiomyopathies and Congestive Heart Failure, run by The Cleveland Clinic 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 3 inclusion and 1 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: stopped early, as of the sponsor's last update on 9 Mar 2022. 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?

Yes. Results are posted in the registry (first posted 9 Mar 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

QRS Frequency at Each Paced Location (time frame: Baseline). 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 9 Mar 2022.
