Abstract

4D flow has been studied in patients with bicuspid aortic valve as their abnormal flow dynamics might relate to the
progression of ascending aortic dilatation. In this study we could perform 4D flow of the thoracic aorta with k-t VD
acceleration methods. 4D flow MRI can offer flow information although the pressure information cannot be obtained.
For better understanding and characterization of aortic biomechanical properties, we combined the 4D flow stroke
volume and brahical cuff estimated CPP to evaluate large vessel compliance. The compliance and PWVs showed an
acceptable agreement. The limitation is the small number of patients in our study.
The focally elevated WSS that we have shown is supposed to influence vessel wall remodeling although further follow
up and pathological studies are necessary to this end.
