About this study

Official title: RECORD TAVR REGISTRY: Prospective, Multi-Center Registry of "Real World" Chinese Patients Undergoing Transcatheter Aortic Valve Replacement

The purpose of this prospective multi-center, observational registry in China is to collect clinical baseline, procedural, and follow-up data of all patients treated with TAVR in China and to evaluate short-, mid-, and long-term clinical outcome data of all post-marketing transcatheter valves. Each center will collect baseline and procedural data as well as clinical outcomes for up to 10 years.

Read the detailed description

Aortic stenosis is the most clinically important valvular heart disease in the elderly, with severe aortic stenosis accounting for about 3.4%-5% of elderly patients. Patients with chest pain, congestive heart failure, or syncope who do not undergo surgical intervention have a poor prognosis, with a 1-year mortality rate as high as 50%. However, the high surgical risk of surgical valve replacement for elderly patients with multiple underlying diseases limits the use of surgical valve replacement, and the prognosis of high-risk surgical patients is poor. The PARTNER series of studies and the US CoreValve high-risk studies confirm that perioperative and postoperative adverse events in patients undergoing TAVR in surgical high-risk patients are comparable to those in surgical valve replacement. With technological advances, the indications for TAVR have been expanded from surgical high-risk to low to moderate-risk populations. Based on the PARTNER 3 and Evolut Low Risk studies, FDA approved the use of TAVR to treat low surgical risk patients with symptomatic severe aortic stenosis. Recently, TAVR has also been expanded to patients with aortic valve regurgitation.

With a population of 1.4 billion, China has a large number of patients with aortic valve disease, but the TAVR program was launched in 2010. No large-scale TAVR studies are available to validate the efficacy and safety of TAVR in the Chinese population. The morphological characteristics of valves in our patients bring great challenges to the operation and application of TAVR. However, through the efforts of Chinese experts and scholars, TAVR technology in China has developed rapidly, and various domestic valves with independent intellectual property have been marketed, bringing new opportunities for the promotion and application of TAVR in China. Domestic valves have been designed for the Chinese aortic valve anatomy, which is theoretically more suitable for the Chinese population. However, the efficacy and safety of these valves still need to be further confirmed in large clinical studies.

This multi-center registry study aims to evaluate the safety and efficacy of all post-marketing transcatheter valves in Chinese patients with aortic valve disease mixed. Investigators will collect baseline and procedural data, and evaluate the short-, mid-, and long-term clinical outcomes of TAVR in a large real-world population.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transcatheter aortic valve replacementProcedure or surgery

    Also called Transcatheter aortic valve implantation

    A total of 3000 consecutive patients with aortic valve disease undergoing TAVR will be enrolled at 30-50 centers. The devices used will be all post-market transcatheter aortic valves approved for use in China. Clinical follow-up will be conducted in the periprocedural and after aortic valve implantation at 1 month, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, and 10 years

What is being measured

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

  1. Combined early safety and clinical efficacy outcomes as defined by the Valve Academic Research Consortium-3 (VARC-3)

    Composed by all-cause mortality, all strokes, any hospitalization, myocardial infarction

    Measured: 1 year

Secondary outcomes (5)
  1. Combined early safety and clinical efficacy outcomes as defined by the Valve Academic Research Consortium-3 (VARC-3)

    Composed by all-cause mortality, all strokes, any hospitalization, myocardial infarction, acute kidney injury, life-threatening or fatal bleeding, mild or greater prosthetic valve regurgitation, new permanent pacemaker implantation, conduction block and arrhythmia, vascular and access-related complications, structural cardiac complications, any other adverse events

    Measured: 30 days

  2. Rate of technical success

    Technical success

    • Freedom from mortality
    • Successful access, delivery of the device, and retrieval of the delivery system
    • Correct positioning of a single prosthetic heart valve into the proper anatomical location
    • Freedom from surgery or intervention related to the devicea or to a major vascular or access-related, or cardiac structural complication

    Measured: at exit from procedure room

  3. Rate of device success

    Device success

    • Technical success
    • Freedom from mortality
    • Freedom from surgery or intervention related to the device or to a major vascular or access-related or cardiac structural complication
    • Intended performance of the valve (mean gradient <20mmHg, peak velocity <3 m/s, Doppler velocity index >_0.25, and less than moderate aortic regurgitation)

    Measured: discharge or 30 days

  4. Combined safety and clinical efficacy outcomes as defined by the Valve Academic Research Consortium-3 (VARC-3)

    Composed by all-cause mortality, all strokes, any hospitalization, myocardial infarction, life-threatening or fatal bleeding, mild or greater prosthetic valve regurgitation, new permanent pacemaker implantation, conduction block and arrhythmia, any other adverse events

    Measured: 2 years, 3 years, 4 years

  5. Combined safety and clinical efficacy outcomes as defined by the Valve Academic Research Consortium-3 (VARC-3)

    Composed by all-cause mortality, all strokes, any hospitalization, myocardial infarction, life-threatening or fatal bleeding, mild or greater prosthetic valve regurgitation, new permanent pacemaker implantation, conduction block and arrhythmia, structural valve deterioration, any other adverse events

    Measured: 5 years and 10 years

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Valve Disease Mixed, run by Xijing Hospital at 1 site in China.

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 2 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 19 Apr 2024. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rutao Wang, M.D, Ph.D (+86-15091095796, rutaowang@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Combined early safety and clinical efficacy outcomes as defined by the Valve Academic Research Consortium-3 (VARC-3) (time frame: 1 year). 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 19 Apr 2024.
