Does Turbulent Kinetic Energy assessed by 4D Flow MRI provide additional information relative to echocardiography for determining aortic stenosis severity in patients with moderate to severe AS?
Multipoint 4D flow MRI assessment of turbulent kinetic energy provides complementary information to echocardiography for evaluating moderate to severe aortic stenosis, particularly in patients with bicuspid valves or dilated aortas.
Elevated TKE levels imply higher energy losses associated with bicuspid aortic valves and dilated ascending aortic geometries that are not assessable by current echocardiographic measures. These findings indicate that TKE may provide complementary information to echocardiography, helping to distinguish within the heterogeneous population of patients with moderate to severe AS.
