A 1D lumped-parameter/3D CFD approach for pressure drop in the aortic coarctation
(Springer, 2012)
Conference report
Restricted access - publisher's policyAortic Coarctation is a congenital constriction of the aorta that increases blood pressure above the constriction and hinders the flow below it. Based on a 3D surface mesh of a moderate thoracic coarctation, a high quality ... -
A multi-method approach towards understanding the pathophysiology of aortic dissections – the complementary role of in-silico, in-vitro and in-vivo information
(Springer, 2010)
Part of book or chapter of book
Restricted access - publisher's policyManagement and follow-up of chronic aortic dissections continues to be a clinical challenge due to progressive aortic dilatation. To predict dilatation, guidelines suggest follow-up of the aortic diameter. However, dilatation ... -
