Measuring aortic wall strength and thickness in ascending aortic aneurysms
Official title: Strength Tracking From Wall Tichness Over Aortic Biomechanics
Run by IRCCS Policlinico S. Donato · NCT07453251 · Data updated 2026-11-12
This project tests whether measuring the strength and thickness of removed ascending aortic tissue can help predict rupture risk for patients having surgery for aortic root or ascending aortic aneurysms.

Is this trial a fit for you?
✓Likely a good fit
Adults scheduled for elective cardiac surgery to remove an ascending aortic or aortic root aneurysm who can provide written informed consent are ideal candidates.
✕Probably not a fit
Patients who have had prior cardiac surgery or who present with acute aortic conditions (such as acute dissection or intramural hematoma) are excluded and would not receive benefit from participating.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational project analyzes resected ascending aortic tissue from patients undergoing surgery for aortic root or ascending aortic aneurysms. Samples undergo standardized mechanical testing (tensile strength, stiffness) and wall-thickness measurement in the lab. Those biomechanical results will be compared with clinical and imaging data such as aortic diameter and valve morphology to look for correlations. The goal is to standardize measurements and determine whether biomechanical data add information about aortic fragility beyond diameter alone.
Why it matters
Potential benefit: If successful, this work could provide surgeons an extra objective measure of aortic fragility to help time operations and counsel patients.
How similar studies have gone: Previous laboratory and computational studies have measured aortic wall biomechanics and reported links to tissue fragility, but these findings have not yet become widely used clinical decision tools.
