Trial summary

In heart failure patients we hypothesised that right ventricular high posterior septum is superior to right ventricular apex in CRT and DDD pacemaker. In two separate trials we prospectively randomized the right ventricular lead placement to find evidence of differences in heart failure symptoms (NYHA-class), 6 minute… Read more about this study

About this study

Official title: Echocardiographic Dyssynchrony in Heart Failure in CRT; Right Ventricular Apex v.s. High Posterior Septum

In heart failure patients we hypothesised that right ventricular high posterior septum is superior to right ventricular apex in CRT and DDD pacemaker. In two separate trials we prospectively randomized the right ventricular lead placement to find evidence of differences in heart failure symptoms (NYHA-class), 6 minute hall walk and echocardiographic measurements of reverse remodelling and dyssynchrony.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CRT in heart failure; Right ventricular apex v.s. high posterior septum in people with Heart Failure, run by Haukeland University Hospital at 1 site in Norway.

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 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: status not confirmed, as of the sponsor's last update on 24 May 2011. 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 Norway. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

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?

Echocardiographic reverse remodelling and dyssynchrony (time frame: 3, 6, 12, 18 and 24 months). 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 NCT01035489, which also lists 3 linked publications.

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 24 May 2011.
