The purpose of this pilot study is to investigate whether myocardial relaxation times (T1 and T2), alter over time in patients with severe aortic valve stenosis, from pre-surgery to 12 months after aortic valve replacement. Myocardial relaxation times were measured pre surgery, and 3 months and 12 months post surgery with 3D-QALAS, T1-MOLLI and T2-GraSE. The results demonstrated significant changes in myocardial relaxation times over time after surgery in this patient group.
