Biventricular Remodeling in Transcatheter Tricuspid Valve Replacement - Acute Hemodynamic Instability Study (TTVR-AHI)

February 10, 2026 updated by: Columbia University

Biventricular Remodeling in Transcatheter Tricuspid Valve Replacement

TTVR-AHI is a multicenter, retrospective registry including heart failure patients displaying a severe and symptomatic tricuspid regurgitation (TR), deemed non-eligible to cardiac surgery and therefore treated with transcatheter tricuspid valve replacement (TTVR) devices. This substudy of the main registry will focus on those with post-procedural acute hemodynamic instability (AHI).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

TTVR-AHI is an international, multicenter, retrospective registry collecting routine clinical and echocardiographic data, on top of a dedicated analysis of the preprocedural CT-scan using Laralab® software. Patients with AHI will be compared to a control group without AHI, composed of individuals implanted with TTVR at Columbia University Irving Medical Center. In this substudy at Columbia, the investigators aim to describe AHI incidence, its clinical presentation, its impact on prognosis, and the predictors of its occurrence.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study population represents TTVR patients presenting specifically an AHI after their intervention. In turn, the control group includes an all-comer population undergoing TTVR.

Description

Inclusion Criteria:

  • Patients implanted with TTVR: Evoque valve system (Edwards Lifesciences), and all other device in the setting of compassionate use And
  • Patients presenting an AHI, defined by the need for inotrope and/or vasopressor support within 24 hours after the procedure due to hemodynamic instability (according to local investigator's judgement).

Exclusion Criteria:

  • Major procedural complication explaining hemodynamic situation (bleeding, tamponade, etc. )
  • Patients started on inotrope/vasopressor either as part of a routine post-interventional protocol or preventively for "right ventricular (RV) support" without sign of hypoperfusion.

Cohorts and Interventions

Group / Cohort

Group / Cohort

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mortality Rate
Time Frame: 1 Year
The prognosis of AHI after TTVR will be measured as the rate of all cause mortality in comparison to the control group.
1 Year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Coronary Artery Disease (CAD)
Time Frame: Baseline (Day 0)

Provide a multimodality description of the AHI population in comparison to the control group by defining the specificities of the AHI population.

The number of participants with CAD will be reported.
Baseline (Day 0)
Number of Participants with Right Ventricular (RV) Dysfunction
Time Frame: Baseline (Day 0)

Provide a multimodality description of the AHI population in comparison to the control group by defining the specificities of the AHI population.

The number of participants with RV dysfunction will be reported.
Baseline (Day 0)
Number of Participants with Pulmonary Hypertension
Time Frame: Baseline (Day 0)
Provide a multimodality description of the AHI population in comparison to the control group by defining the specificities of the AHI population. The number of participants with pulmonary hypertension will be reported.
Baseline (Day 0)
Number of Participants with Primary Left Ventricular Cardiomyopathy
Time Frame: Baseline (Day 0)
Provide a multimodality description of the AHI population in comparison to the control group by defining the specificities of the AHI population. The number of participants with primary left ventricular cardiomyopathy will be reported.
Baseline (Day 0)
Number of Participants with Post-Procedural Fever
Time Frame: Within 48 hours after the procedure
The number of participants with post-procedural fever will be reported and used to define the factors associated with the occurrence of AHI after TTVR in multivariable analysis.
Within 48 hours after the procedure
Number of Participants with Post-procedural Inflammatory Response
Time Frame: Within 48 hours after the procedure

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
