Journal ArticleDOI
Numerical simulation of the dynamics of a bileaflet prosthetic heart valve using a fluid–structure interaction approach
Matteo Nobili,Umberto Morbiducci,Raffaele Ponzini,Costantino Del Gaudio,Antonio Balducci,Mauro Grigioni,Franco Maria Montevecchi,Alberto Redaelli +7 more
TL;DR: The favorable agreement obtained between in vitro and in silico results of the leaflet displacements confirms the consistency of the numerical method used, and candidates the application of FSI models to become a major tool to optimize the MHV design and eventually provides useful information to surgeons.
Journal ArticleDOI
ZebraBeat: a flexible platform for the analysis of the cardiac rate in zebrafish embryos
embryos De Luca,Gian Maria Zaccaria,Marwa M. A. Hadhoud,Giovanna Rizzo,Raffaele Ponzini,Umberto Morbiducci,Massimo Santoro,Massimo Santoro +7 more
TL;DR: It is shown here that this platform, called ZebraBeat, can successfully detect heart rate variations in embryonic zebrafish at various developmental stages, and it can record cardiac rate fluctuations induced by factors such as temperature and genetic- and chemical-induced alterations.
Journal ArticleDOI
Outflow Conditions for Image-Based Hemodynamic Models of the Carotid Bifurcation: Implications for Indicators of Abnormal Flow
Umberto Morbiducci,Diego Gallo,Diana Nada Caterina Massai,Filippo Consolo,Raffaele Ponzini,Luca Antiga,Cristina Bignardi,Marco Agostino Deriu,Alberto Redaelli +8 more
TL;DR: The findings underscore that the overall effect of the assumptions done in order to simulate blood flow within the carotid bifurcation is mainly in the hot-spot modulation of the hemodynamic descriptors of atherosusceptible areas, rather than in their distribution.
Journal ArticleDOI
On the importance of blood rheology for bulk flow in hemodynamic models of the carotid bifurcation.
Umberto Morbiducci,Diego Gallo,Diana Nada Caterina Massai,Raffaele Ponzini,Marco Agostino Deriu,Luca Antiga,Alberto Redaelli,Franco Maria Montevecchi +7 more
TL;DR: The findings suggest that the assumption of Newtonian rheology could be reasonable for bulk flow metrics and influences at different levels the WSS-based indicators, depending on the bifurcation model, even if in this study it is lower than the major source of uncertainty.
Journal ArticleDOI
A rational approach to defining principal axes of multidirectional wall shear stress in realistic vascular geometries, with application to the study of the influence of helical flow on wall shear stress directionality in aorta
Umberto Morbiducci,Diego Gallo,Simone Cristofanelli,Raffaele Ponzini,Marco Agostino Deriu,Giovanna Rizzo,David A. Steinman +6 more
TL;DR: The projection scheme confirmed its consistency and plausibility in realistic arterial geometries and allowed to get insight into the relationship between aortic intravascular fluid structures and WSS directionality.
