Hemodynamic characteristics of dilated ascending aorta in patients with bicuspid aortic valve.

ABSTRACT:

Background

The aim of this study is to investigate the influence of aortic diameter on hemodynamic environment characteristics in patient with the bicuspid aortic valve (BAV) and dilated ascending aorta (AAo).

Method

In this study, an MRI of one BAV patient with 4.5 cm AAo was collected and numerical model was constructed. Based on the images, three additional anatomical models were constructed with different AAo sizes of 4.0 cm, 5.0 cm and 5.5 cm respectively, while the size and the geometry of other parts were fixed. Then hemodynamics in these four models was simulated numerically and the flow patterns and loading distributions were investigated.

Result

Hemodynamics environments in the AAo were simulated with different aortic sizes. As the aortic diameter increases,
