"Development of computational methods for personalised assessment of the biomechanical functions of the Marfan aorta"
Marfan syndrome is a genetic disorder of connective tissue which is associated with progressive aortic root dilatation and increased aortic wall stiffness. If left untreated it could lead to aortic dissection – the leading cause of death in Marfan patients. One of the methods developed to prevent progressive dilatation is the insertion of a personalised external aortic root support (PEARS).
The aim of this research is to evaluate the biomechanical implications of the PEARS. This will be done using combined medical image processing (MRI and PC-MRI) and computational fluid and structural mechanics. Models will be developed and analysed using various in-house programs and commercial software including Mimics, Matlab, ANSYS and Ensight.
