Abstract
Management 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 is triggered by haemodynamic parameters (pressure and wall shear stresses (WSS)), and geometry of false (FL) and true lumen (TL). We aimed at a better understanding of TL and FL haemodynamics by performing in-silico (CFD) and in-vitro studies on an idealized dissected aorta and compared this to a typical patient. We observed an increase in diastolic pressure and wall stress in the FL and the presence of diastolic retrograde flow. The inflow jet increased WSS at the proximal FL while a large variability in WSS was induced distally, all being risk factors for wall weakening. In-silico, in-vitro and in-vivo findings were very similar and complementary, showing that their combination can help in a more integrated and extensive assessment of aortic dissections, improving understanding of the haemodynamic conditions and related clinical evolution.

A reduced-order model based on the coupled 1D-3D finite element simulations for an efficient analysis of hemodynamics problems
E. Soudah, R. Rossi, S. Idelsohn, E. Oñate

Computational Mechanics (2014). Vol. 54 (4), pp. 1013-1022

Abstract
A reduced-order model for an efficient analysis of cardiovascular hemodynamics problems using multiscale approach is presented in this work. Starting from a patient-specific computational mesh obtained by medical imaging techniques, an analysis methodology based on a two-step automatic procedure is proposed. First a coupled 1D-3D Finite Element Simulation is performed and the results are used to adjust a reduced-order model of the 3D patient-specific area of interest. Then, this reduced-order model is coupled with the 1D model. In this way, three-dimensional effects are accounted for in the 1D model in a cost effective manner, allowing fast computation under different scenarios. The methodology proposed is validated using a patient-specific aortic coarctation model under rest and non-rest conditions.

Validation of numerical flow simulations against in vitro phantom measurements in different type B aortic dissection scenarios

Abstract
An aortic dissection (AD) is a serious condition defined by the splitting of the arterial wall, thus generating a secondary lumen [the false lumen (FL)]. Its management, treatment and follow-up are clinical challenges due to the progressive aortic dilatation and potentially severe complications during follow-up. It is well known that the direction and rate of dilatation of the artery wall depend on haemodynamic parameters such as the local velocity profiles, intra-luminal pressures and resultant wall stresses. These factors act on the FL and true lumen, triggering remodelling and clinical worsening. In this study, we aimed to validate a computational fluid dynamic (CFD) tool for the haemodynamic characterisation of chronic (type B) ADs. We validated the numerical results, for several dissection geometries, with experimental data obtained from a previous in vitro study performed on idealised dissected physical models. We found a good correlation between CFD simulations and experimental measurements as long as the tear size was large enough so that the effect of the wall compliance was negligible.

Computational fluid dynamics indicators to improve cardiovascular pathologies diagnosis
E. Soudah, E. Oñate, M. Cervera

Monograph CIMNE (2016). M167

Abstract
In recent years, the study of computational hemodynamics within anatomically complex vascular regions has generated great interest among clinicians. The progress in computational fluid dynamics, image processing and high-performance computing have allowed us to identify the candidate vascular regions for the appearance of cardiovascular diseases and to predict how this disease may evolve. In this monograph we attempt to introduce into medicine the computational predictive paradigm that has been used in engineering for many years. Several groups have tried to create predictive models for cardiovascular pathologies, but they have not yet begun to use them in clinical practice. Our final aim is to go further and obtain predictive variables to be used in the clinical field. We try to predict the evolution of aortic abdominal aneurysm, aortic coarctation and coronary artery disease in a personalized way for each patient. We propose diagnostic indicators that can improve the diagnosis and predict the evolution of the disease more efficiently than the methods used until now. In particular, a new methodology for computing diagnostic indicators based on computational hemodynamics and medical imaging is proposed. We have worked with data of anonymous patients to create real predictive technology that will allow us to continue advancing in personalized medicine and generate a more sustainable health systems. The objective of this monograph is therefore to develop predictive models for cardiovascular pathologies by merging medical imaging and computational techniques at a clinical level. It is expected in the near future that larger databases of patient-specific computational models will be available to doctors. These data can be used with predictive models to improve diagnosis and to define personalized therapies and treatments.

Anatomía computacional: una metodologia eficiente basada en imágenes médicas para la generación de modelos 3D
G. Gavidia, M. Martín-Landrove, M. Cerrolaza, E. Soudah

Monograph CIMNE (2011). M125

Abstract
Este libro está orientado a introducir en los conceptos generales de la reconstrucción 3D de estructuras anatómicas y presentar una metodología para la obtención de modelos geométricos de tejidos del cuerpo humano a partir de imágenes médicas, útiles para su discretización con los métodos numéricos, con el objetivo de poder simular su comportamiento y planificar intervenciones quirúrgicas. Para este fin, se implementaron diferentes técnicas de procesamiento en imágenes médicas de diversas modalidades, lo que nos permitió obtener geometrías precisas de los tejidos de interés en un corto tiempo de procesamiento. La amplia gama de estudios basados en la reconstrucción tridimensional de tejidos del ser humano a partir de las imágenes médicas, demuestran que éstas han revolucionado los métodos clínicos de diagnosticar y tratar las enfermedades. No sólo permiten a los médicos y científicos obtener información vital observando el interior del cuerpo humano de una manera no invasiva, además, combinadas con técnicas de procesamiento digital, constituyen herramientas para la obtención de modelos geométricos de nuestro cuerpo más precisos sin necesidad de ingresar al paciente.
