Abstract

In an age of increased demand for cardiovascular interventions – surgical but also minimally invasive – there is an urgent need for improved and reliable prognostics in patients presenting with abdominal aortic aneurysms. Is it possible to inform predictions of rupture risk using biomedical imaging data direct from the clinic? This work builds on pre-existing simplified computational models that couple the fluid dynamics of blood with the structural dynamics of aortic tissue.
