About this study
Official title: Regional, Multicentric Registry of Aortic Valve-sparing Root Replacement, According to the Inclusion Technique Described by Tirone David
Retrospective observational study of all patients undergoing aortic root surgery with aortic valve conservation, using the inclusion technique described by Tirone David, between January 1, 2004 and December 31, 2020, at six centers (Nantes - Rennes - Brest - Angers - Tours [two centers]). The main objective of this study is to evaluate the survival without re-intervention for aortic valve dysfunction (surgery or TAVI).
Read the detailed description
Retrospective observational study of all patients undergoing aortic root surgery with aortic valve conservation, using the inclusion technique described by Tirone David.
Inclusion criteria: Patients undergoing aortic root surgery with conservation of the aortic valve, according to the inclusion technique described by Tirone David, between January 1, 2004 and December 31, 2020, at one of the six centers: Nantes, Rennes, Brest, Angers, Tours (two centers).
Non-inclusion criteria: Prosthetic replacement of the aortic valve intraoperatively during the first operation.
Objectives and endpoints :
- The survival without re-intervention for aortic valve dysfunction (surgery or TAVI)
- The overall cardiovascular survival
- The survival without aortic insufficiency of grade equal to or greater than two
- The survival without aortic infective endocarditis
- Assessment of long-term stroke risk Assessment of the risk of a major bleeding event in the long term Data analysis : The AORTLANTIC study is included in the EPICARD registry which is the official, national database of the French Society of Cardiac Surgery. Study data will then be collected using EPICARD's electronic Case Report Form (eCRF) and then analyzed using a multivariate Cox model. For the follow-up, the WEPI eCRF is used.

Questions about this trial
What is this clinical trial studying?
An observational study of Aortic Root Aneurysm and Aortic Regurgitation, run by Nantes University Hospital at 5 sites in France.
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 3 inclusion and 0 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 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in France. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Evaluate the survival without re-intervention for aortic valve dysfunction (surgery or TAVI), after aortic root surgery with conservation of the aortic valve, according to the inclusion technique described by Tirone David (time frame: Conditional survival starting at 30 days). 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 16 Oct 2026.
