Trial summary

In individuals needing a left ventricular assist device (LVAD), right heart failure (RHF) is a serious complication post-surgery, associated with worsened outcomes including mortality. However, predictors of decompensation after LVAD are not well established. Read more about this study

About this study

Official title: Shear Wave Elastography of the Liver and Predictions of Morbidity and Mortality in Subjects Undergoing Advanced Heart Failure Therapy

In individuals needing a left ventricular assist device (LVAD), right heart failure (RHF) is a serious complication post-surgery, associated with worsened outcomes including mortality. However, predictors of decompensation after LVAD are not well established. Liver dysfunction pre-LVAD has been shown to be associated with poor outcomes post-LVAD, but the interplay between liver abnormalities and RHF post-LVAD is not well characterized. Liver stiffness (LS) is a measure associated with certain types of liver abnormalities (e.g., liver fibrosis; cirrhosis).

Thus, we hypothesize that elevated LS measured by SWE is associated with increased morbidity and mortality in patients undergoing LVAD implantation and yields increased need for advanced postoperative HF therapies including the use of right ventricular assist devices (RVAD) for the management of RHF.

PRESTUDY ASSESSMENTS Note: Assessments that are part of the standard of care and obtained within 3-4 weeks of prestudy assessment visit, are acceptable as part of the screening tests. Results of such tests will be acceptable even if obtained prior to the execution of the Informed Consent.

Prior to entry into the study, the following assessments will be performed to determine if patient is eligible to continue in the study as per section 4.2 and 4.3 describing the inclusion and exclusion criteria for the study.

  1. A signed Patient Informed Consent Form must be obtained.
  2. A signed Patient Authorization Form (HIPAA) must be obtained.
  3. It has been confirmed that the patient meets all inclusion criteria and none of the exclusion criteria.
  4. Assessment of concomitant medications must be obtained within 4 weeks prior to registration.

ASSESSMENTS DURING STUDY

The following evaluations will be performed during the study:

  1. An assessment of liver stiffness will be performed by shear wave elastography using a Supersonic Imagine Aixplorer ShearWave™ ultrasound machine. Liver stiffness assessment will be performed at a baseline visit (i.e., before LVAD placement for those undergoing LVAD therapy), and if feasible at 1 month and 6 months post-therapy (for those undergoing advanced therapy [i.e., LVAD or transplant]) or at 1 month and 6 months post-baseline (for those not undergoing advanced therapy.) FOLLOW UP ASSESSMENTS The duration of patient participation in the study will be a total of 12 months, which is counted from LVAD placement (or from baseline, for those not undergoing LVAD therapy). Follow-ups will be performed at 1 month, 6 months, and 12 months, during which the following information will be documented on the CRF.

Note: Patients who die or withdraw consent are considered off study and no further information will be collected.

What is being measured

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

  1. Liver stiffness (LS) measurements with development of post-LVAD RHF.

    An assessment of liver stiffness will be performed by shear wave elastography using a Supersonic Imagine Aixplorer ShearWave™ ultrasound machine.

    Measured: 24 months

Secondary outcomes (2)
  1. 30 day in-hospital mortality rate

    We will perform logistic regression to determine the optimal cutpoint of LS to predict mortality at a given time point, provided the sample size is adequate.

    Measured: 30 days

  2. 1 year mortality rate

    We will perform logistic regression to determine the optimal cutpoint of LS to predict mortality at a given time point, provided the sample size is adequate.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure and Transplant; Failure, Heart, run by Baylor Research Institute 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 5 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 26 Jan 2023. 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?

Liver stiffness (LS) measurements with development of post-LVAD RHF. (time frame: 24 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 26 Jan 2023.
