Trial summary

The purpose of the trial is to identify factors which can be used as guidance when optimizing continuous-flow left ventricular assist device (CF-LVAD) settings. The hypothesis of the study is that pulmonary capillary wedge pressure (PCWP) will change independently of left ventricular end diastolic diameter (LVEDD)… Read more about this study

About this study

The purpose of the trial is to identify factors which can be used as guidance when optimizing continuous-flow left ventricular assist device (CF-LVAD) settings.

The hypothesis of the study is that pulmonary capillary wedge pressure (PCWP) will change independently of left ventricular end diastolic diameter (LVEDD) when increasing pump speed ie ΔPCWP/RPM ≠ ΔLVEDD/RPM.

The primary combined endpoint of the study is correlation between ΔPCWP and LVEDD slope under ramp testing in a cohort of "continuous-flow left ventricular assist device" heart failure patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure., run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 5 inclusion and 3 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 28 Oct 2015. 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 Denmark. 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?

Pulmonary capillary wedge pressure in mmHg. (time frame: On trial day.). 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 28 Oct 2015; AzTrials last refreshed its copy on 28 Oct 2026.
