About this study
Official title: Early and 1-year Hemodynamic Performance and Clinical Outcomes After Aortic Valve Replacement Using Two Pericardial Bioprostheses: A Multicenter Randomized Controlled Trial
The purpose of the study is to compare early and 1-year hemodynamic performance and clinical outcomes after aortic valve replacement using two pericardial bioprosthesis, Avalus and Carpentier Edwards Perimount Magna Ease.
Read the detailed description
This trial was designed as a multicenter randomized, controlled trial to recruit 386 patients who undergo aortic valve replacement with pericardial bioprosthesis. Patients were randomized by use of a randomization table. Bioprosthesis was chosen between Avalus or Carpentier Edwards Perimount Magna Ease according to the randomization result. The primary end point is postoperative 1-year transvalvular mean pressure gradient. The secondary end points are postoperative 1-year effective orifice area, operative mortality, operative morbidities, 1-year overall survival, 1-year freedom from cardiac death and 1-year freedom from valve-related events.

Questions about this trial
What is this clinical trial studying?
A study testing AVR with AVALUS and AVR with CEPME in people with Aortic Valve Disease, run by Seoul National University Hospital at 2 sites in South Korea.
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 1 inclusion and 5 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: finished, as of the sponsor's last update on 8 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in South Korea. 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?
Yes. Results are posted in the registry (first posted 8 Feb 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Transvalvular Mean Pressure Gradient (mPG) (time frame: at postoperative 1 year). 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 NCT03796442, which also lists 2 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 8 Feb 2023; AzTrials last refreshed its copy on 7 Nov 2026.
