Abstract:
Background. In vivo experimentation is the most realistic approach for exploring the vascular biological response to the hemodynamic stresses that are present in life. Post-mortem vascular casting has been used to define the in vivo geometry for hemodynamic simulation; however, this procedure damages or destroys the tissue and cells on which biological assays are to be performed. Method of Approach. Two statistical approaches, regional (RSH) and linear (LSH) statistical hemodynamics, are proposed and illustrated, in which flow simulations from one series of experiments are used to define a bes

Abstract:
Abstract For hemodynamic simulations of intracranial aneurysms boundary conditions (BC) are required. In most cases, these are not patient-specific and thus do not reflect the real flow conditions in the patient. This study investigates the influence of patient-specific inflow BC on intra-aneurysmal hemodynamics. The focus lies on gender and age variations of the patients. To asses the impact, four different inflow curves representing the velocity profile of the inflow over one cardiac cycle is modeled. These four inflow BC are varied in the simulations of each aneurysm from selected subgroups

The paper describes the modeling technology and the main results of the simulation of hemodynamic effects of cardiac hypertrophy (HH), conducted using previously published mathematical model (MM) [9]. The dynamics of hemodynamic abnormalities are not modeled. MM simulates changes in the central hemodynamics at different degrees and forms of myocardial hypertrophy (MH). Software technology provides a simulation of three types of HH: a) adaptive HH arising in response to the chronic lack of the systemic circulation; b) abnormal HH, which is at the extreme stage of adaptive HH; c) abnormal MH of

Abstract:
Hemodynamic simulations are increasingly used to study vascular diseases such as Intracranial Aneurysms (IA) and to further develop treatment options. However, due to limited data, certain aspects must rely on heuristics, especially at the simulation’s distal ends. In the literature, Murray’s Law is often used to model the outflow split based on vessel cross-section area; however, this poses challenges for the communicating arteries in the Circle of Willis (CoW). In this study, we contribute by assessing the impact of Murray’s Law in patient-specific geometries featuring IA at the posterior co

Abstract:
An aneurysm is a vascular malformation that can be classified according to its location (cerebral, aortic) or shape (saccular, fusiform, and mycotic). Recently, the study of blood flow interaction with aneurysms has gained attention from physicians and engineers. Shear stresses, oscillatory shear index (OSI), gradient oscillatory number (GON), and residence time have been used as variables to describe the hemodynamics as well as the origin and evolution of aneurysms. However, the causes and hemodynamic conditions that promote their growth are still under debate. The present work presents numer

Abstract Introduction: In this study, phase-contrast magnetic resonance imaging (PC-MRI) 4D flow data for patients with bicuspid aortic valve (BAV) were analyzed based on the spatial resolution of the images. BAV is a congenital heart defect characterized by the presence of two cusps in the aortic valve, leading to various complications. PC-MRI is a noninvasive imaging technique used to assess the hemodynamics in patients. However, interpretation of PC-MRI data can be challenging due to complex hemodynamics, which makes numerical simulations necessary to complement the results. Methods:Within

Abstract Much of the recent work attempting to simulate arterial flows has been motivated by attempts to elucidate the relationship between flow in the arteries and atherogenesis, and the focalization of plaque development. The aspect of the flow of most interest in this context was wall shear stresses, there being substantial evidence that the most susceptible sites are where shear stresses are low, or change rapidly in time or space [1]. These conditions are most likely to occur where there are sudden changes in flow geometry, and/or when the flow is unsteady. (For a recent review see [2].)
