About this study

Official title: Safety, Effectiveness and Durability of Sapien 3 Transcatheter Aortic Valve Replacement in Young Aortic Valve Stenosis Patients From China

Safety, effectiveness and durability of Sapien 3 transcatheter aortic valve replacement in young aortic valve stenosis patients from China:A multi-center, retrospective and prospective, single arm, observational study

Read the detailed description

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of patients with severe aortic stenosis (AS). Currently TAVR indication has expanded to intermediate and low-risk patients from inoperable or high-risk patients, through a rigorous series of clinical trials comparing TAVR with surgical aortic valve replacement (SAVR).

Despite 2020 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines recommended SAVR for patients with symptomatic severe AS aged <65 years, the previous data from United States nationwide Vizient Clinical Data Base and Northern New England Cardiovascular Disease Group Consortium (NNECDSG) registry demonstrated dramatic growth in TAVR utilization in younger patients aged <65 years from 2015 to 2021/2022, which is possibly driven by increased TAVR utilization in low surgical risk patients.

However, TAVR has never been systematically tested in young (<65 years old), low-risk patients, with many unanswered questions, especially the safety and effectiveness of TAVR in patients with bicuspid aortic valves and the durability of transcatheter heart valves. Furthermore, we noticed that the patients between 65 years old and 70 years old accounted for 23.3% of all the TAVR patients and this patient subgroup were underrepresented in the previous study, which makes it necessary to also explore the interested endpoints in this subgroup.

The aim of this study is to establish the safety and efficacy of Sapien 3 TAVR in young (50~70 years old) Chinese patients with severe symptomatic AS, including Type-1 bicuspid population and to explore the durability performance of Sapien 3 in this cohort.

What participants receive

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

  • Transcatheter Aortic Valve Replacement (TAVR)Procedure or surgery

    TAVR procedure was performed according to standard clinical practice. Successful vascular access, delivery and deployment of the device and successful retrieval of the delivery system will be attempted. Vascular access site will be through transfemoral on the basis of pre-procedural evaluation of access site vessel. The procedure will be performed under local or general anesthesia and per clinical practice standard.

The record says: looking for participants now, as of the sponsor's last update on 27 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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 Jian Yang, MD, PhD (+8613892828016, yangjian@fmmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

All-cause mortality (time frame: At 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06830499, which also lists 9 linked publications.

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 27 May 2026.
