Prospective Evaluation of the Biomechanical Properties of the Thoracic Aorta Coupling Magnetic Resonance Imaging and In-vitro Elasticity Tests in Patients With Ascending Aortic Aneurysm (MECATHOR)

January 8, 2026 updated by: Centre Hospitalier Universitaire Dijon
The biomechanical properties of the aorta are currently poorly understood. A better understanding would optimize surgical indications and monitoring techniques for patients with thoracic aortic aneurysms.
