The aim of our study was to evaluate the impact of aortic root replacement by a graft on the elastic properties of the descending thoracic aorta using cardiac Magnetic Resonance Imaging (MRI) and automatic post-processing. Nineteen patients were operated on an aortic root aneurysm and a cardiac MRI allowing aortic compliance measurement was performed before and after surgery. Images were acquired with a 1.5 T MRI with only one additional sequence to a conventional aortic MRI protocol.
Observational and retrospective trial on medical data only. The patients are operated of planned aortic root aneurysm without additional intervention. The pre and postoperative cardiac MRI are planned in standard of care.

Patient with planned Ascending aorta replacement with graft
Aortic compliance of descending aorta (mm2/mmHg)
Aortic elastic properties of the descending aorta before and after aortic root replacement using cardiac MRI. Aortic compliance is a local measurement of elastic properties which is obtained with cardiac MRI images by computer processing.
Time frame: post-operative cardiac MRI performing between 12 and 24 months
Aortic compliance of ascending aorta (mm2/mmHg)
Aortic elastic properties of the ascending aorta before and after aortic root replacement using cardiac MRI. Aortic compliance is a local measurement of elastic properties which is obtained with cardiac MRI images by computer processing.
Time frame: post-operative cardiac MRI performing between 12 and 24 months
