Hemodynamic Implications of Transcatheter Tricuspid Valve Repair in HFpEF Patients (HERACLES-HFpEF)

April 14, 2021 updated by: Philipp Lurz, Heart Center Leipzig - University Hospital

Hemodynamic Characterisation of Patients Undergoing Transcatheter Tricuspid Valve Edge-to-edge Repair in Patients With Severe Tricuspid Regurgitation and Heart Failure With Preserved Ejection Fraction

The aim of the study is to investigate the pathophysiological implications of transcatheter tricuspid valve edge-to-edge repair in patient with heart failure and preserved ejection fraction and severe tricuspid regurgitation. Changes in right- and left-ventricular function as well as the interventricular dependence will be analysed on a multimodal basis including pressure-volume loop analysis and cardiac magnetic resonance imaging.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Transcatheter tricuspid valve edge-to-edge repair
Patients will undergo transcatheter tricuspid valve edge-to-edge repair (TTVR) and hemodynamic characteristics will be analysed on a multimodal approach using cardiac magnetic resonance imaging and pressure volume loop analysis before and after TTVR.
Device: Transcatheter tricuspid valve edge-to-edge repair
Transcatheter tricuspid valve edge-to-edge repair is an interventional approach to treat severe tricuspid regurgitation. Under general anesthesia a clip delivery system is forwarded through the vena femoralis and right atrium in the right ventricle. A clip is deployed to clamp the tricuspid valve and reduce tricuspid valve regurgitation.

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
Periprocedural change in enddiastolic pressure volume relationship of the left ventricle
Time Frame: Periprocedural.
Change in the ratio of pressure to volume of the left ventricle before and after TTVR. Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Periprocedural.

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
Change in the estimated left ventricular end diastolic volume at 10 mmHg as estimated by the left ventricular pressure volume relationship (LVEDPVR)
Time Frame: Periprocedural.
Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Periprocedural.
Change in the ratio of isovolumetric relaxation constant "Tau" and duration of diastole of the left ventricle.
Time Frame: Periprocedural.
Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Periprocedural.
Change in dPdtmin
Time Frame: Periprocedural.
Measurement will take place during TTVR with patient in general anesthesia. Measures will be made using a commercially available conductance catheter. Data analysis will be performed offline using a dedicated software.
Periprocedural.
Change in the early diastolic filling pattern as assessed by MRI.
Time Frame: Baseline and 1-month follow-up following TTVR.
All patients will receive MRI before and 1-month after TTVR on a 1.5 tesla scanner.
Baseline and 1-month follow-up following TTVR.
