Trial summary

The purpose of this study is to determine whether using an echocardiogram (a painless test where ultrasound is used to see your heart) while using mild electrical stimulation from your own CRT-D device to stimulate the ventricles (the lower chambers of the heart) to squeeze one slightly earlier than the other will… Read more about this study

About this study

The purpose of this study is to determine whether using an echocardiogram (a painless test where ultrasound is used to see your heart) while using mild electrical stimulation from your own CRT-D device to stimulate the ventricles (the lower chambers of the heart) to squeeze one slightly earlier than the other will show a sustained increase your heart's productivity (Cardiac Output (CO)), following implantation of a Cardiac Resynchronization Device (CRT-D). We believe that squeezing some parts of the heart earlier than others may make the heart a stronger pump.

What is being measured

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

  1. To determine if a sustained hemodynamic benefit of increased Cardiac Output is maintained in patients who undergo ECHO guided optimization of V-V timing following CRT implantation when compared to patients simultaneously biventricularly paced.

    Measured: 6 months

Secondary outcomes (1)
  1. Assessment for improvements in 1)6 minute walk 2)ECHO parameters 3)symptoms as assessed by the Minnesota Quality of Life Score.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing "Sequential Arm" (Promote , model # 2207-36 or Atlas HF , model # V-343) and "Simultaneous Arm" (Promote , model # 2207-36 or Atlas HF , model # V-343) in people with Cardiomyopathy and Heart Failure, run by Duke University 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 6 inclusion and 6 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 1 Aug 2014. 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?

To determine if a sustained hemodynamic benefit of increased Cardiac Output is maintained in patients who undergo ECHO guided optimization of V-V timing following CRT implantation when compared to patients simultaneously biventricularly paced. (time frame: 6 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 1 Aug 2014.
