In this work we propose a mathematical and numerical model to describe the early stages of atherosclerotic plaque formation, which is based on the interaction of processes with different spatial and temporal scales. A fluid–structure interaction problem, used to describe the cardiovascular mechanics arising between blood and the artery wall, is coupled to a set of differential problems describing the evolution of solute concentrations. In order to manage the multiscale-in-space nature of the inv...

We propose a surrogate model for the fluid-structure interaction (FSI) problem for the study of blood dynamics in carotid arteries in presence of plaque. This is based on the integration of a numerical model with subject-specific data and clinical imaging. We propose to model the plaque as part of the tissues surrounding the vessel wall through the application of an elastic support boundary condition. In order to characterize the plaque and other surrounding tissues, such as the close-by jugular...

Introduction: Post-ischemic dilated cardiomyopathy (DCM) is a complex clinical condition characterized by adverse left ventricular (LV) remodeling with impairment of systolic and diastolic function. Standard analyses of DCM include the assessment of LV function through CINE and late gadolinium enhancement (LGE) MRI. Only recently, 4D Flow was proposed to characterize LV function measuring in vivo 3D intraventricular flow. Hypothesis: Integrating CINE, LGE and 4D Flow analysis to comprehensively ...
