Lipid and mitochondrial clues in aortic aneurysm with bicuspid or tricuspid valves
Official title: A Prospective, Single-center, Open-label Study of Lipid Metabolism and Mitochondrial Function in Myeloid Cells and Total Aortic Tissue in Patients With Ascending Thoracic Aortic Aneurysm (ATA) and Bicuspid (BA) or Tricuspid (TA) Aortic Valves.
Run by Centre Hospitalier Universitaire Dijon · NCT07695545 · Data updated 2026-11-12
This study tests whether inflammatory and metabolic signatures in myeloid cells and aortic tissue differ between patients with bicuspid versus tricuspid aortic valves who need surgery for ascending aortic aneurysm.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with ascending aortic aneurysm who are scheduled for surgical repair and have a preoperative confirmation of bicuspid or tricuspid aortic valve.
✕Probably not a fit
Patients who do not have the specified valve morphology, or whose surgery is not performed, may not receive insights from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is an observational study comparing molecular patterns in blood-derived myeloid cells and discarded ascending aortic tissue from patients undergoing surgical repair for ascending aortic aneurysm. The researchers will analyze inflammatory, metabolic, and transcriptomic signatures to identify differences related to valve morphology (bicuspid vs. tricuspid). By collecting additional blood samples and tissue, the study aims to reveal potential biomarkers and targets for therapy related to aneurysm progression. Eligibility focuses on adults planning surgery and confirmed valve architecture, with several exclusions to ensure safety and data quality. No interventional treatments are tested in this design; findings would inform future research and clinical understanding.
Why it matters
Potential benefit: If successful, the study could identify biomarkers or molecular targets that help predict aneurysm progression or inform personalized treatment strategies.
How similar studies have gone: Previous research has shown that valve morphology and inflammatory/metabolic pathways can influence aneurysm biology, supporting the rationale for this comparative approach.
