Tunisian Registry of Trans Catheter Aortic Valve Implantation (TAVI-TN)

November 26, 2024 updated by: Les Laboratoires des Médicaments Stériles

Design and Rationale of the National Multicenter Tunisian Registry of Trans Catheter Aortic Valve Implantation Registry

Transcatheter aortic valve implantation (TAVI) has emerged as a transformative therapy for patients with severe aortic stenosis, particularly those designated high-risk or inoperable for traditional surgical valve replacement. Despite its increasing adoption worldwide, there re-mains a paucity of data regarding TAVI outcomes in Tunisian patients. In response to this gap in knowledge, the investigators propose the establishment of the Tunisian TAVI Registry, a multicenter initiative aimed at comprehensively documenting the clinical characteristics, procedural de-tails, and short- and long-term outcomes of TAVI procedures across Tunisia. The TAVI.TN registry will enroll consecutive patients undergoing TAVI procedures at participating centers across Tunisia, between 2013 and 2024 with a retrospective arm and a prospective arm. The TAVI-TN Registry represents a significant step towards enhancing our understanding of TAVI outcomes in the Tunisian population. By systematically capturing real-world data, this initiative aims to inform clinical decision-making, improve patient care, and contribute to the advancement of TAVI practices in Tunisia and beyond.

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.

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

  • All Tunisian patients already implanted with a TAVI
  • Patients implanted during the period of one year starting from D1 of the registry's launch i.e. 23/09/2023.

Description

Inclusion Criteria:

- Any Tunisian patient who was treated with TAVI implantation in Tunisia

Exclusion Criteria:

  • Patients who are not Tunisians
  • Patients not agreeing to sign consent, witnesses not agreeing to sign consent (family member)

Design Details

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
VARC (Valve Academic Research Consortium-2) defined "Clinical Efficacy" composite endpoint
Time Frame: From 30 days post procedure to completion of at least 2 years of follow up
  • All-cause mortality
  • All stroke (disabling and non-disabling)
  • Requiring hospitalizations for valve-related symptoms or worsening congestive heart failure
  • NYHA (New York Heart Association) class III or IV functional classification of heart failure
  • Valve-related dysfunction (mean aortic valve gradient ≥20 mmHg, Effective Orifice Area (EOA) ≤0.9-1.1 cm2(c) and/or Doppler Velocity Integral (DVI) <0. 35 m/s, AND/OR moderate or severe prosthetic valve regurgitation
From 30 days post procedure to completion of at least 2 years of follow up

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
VARC defined 'Device success' composite endpoint
Time Frame: 30 days
  • Absence of procedural mortality
  • Correct positioning of a single prosthetic heart valve into the proper anatomical location
  • Intended performance of the prosthetic heart valve (no prosthesis - patient mismatch and mean aortic valve gradient ,20 mmHg or peak velocity ,3 m/s, no moderate or severe prosthetic valve regurgitation)
30 days

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 23, 2023

Primary Completion (Estimated)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
