Numerical simulation of left ventricular assist device implantations: comparing the ascending and the descending aorta cannulations

Alfio Quarteroni, Simone Deparis, Adelmo Cristiano Innocenza Malossi, Jean Bonnemain, Matteo Lesinigo, Ludwig Von Segesser

In this work we present numerical simulations of continuous flow left ventricle assist device implantation with the aim of comparing the ascending and the descending aorta anastomosis of outflow cannula. Despite the fact that the second approach is less in ...

Opportunities for Targeting the Angiotensin-Converting Enzyme 2/Angiotensin-(1-7)/Mas Receptor Pathway in Hypertension

It is well known that the renin-angiotensin system (RAS) plays a pivotal role in the pathophysiology of cardiovascular diseases. This is well illustrated by the great success of ACE inhibitors and angiotensin (Ang) II AT(1) blockers in the treatment of hyp ...

Pathophysiological role of the renin-angiotensin system on erectile dysfunction

Nikolaos Stergiopoulos

Background The renin-angiotensin system (RAS) has been shown to play an active role within the erectile tissues. The aim of this narrative review is to summarize the literature addressing the pathophysiological role of RAS on erectile function. Additionall ...

Simulation-based uncertainty quantification of human arterial network hemodynamics

Alfio Quarteroni, Gianluigi Rozza, Peng Chen

This work aims at identifying and quantifying uncertainties from various sources in human cardiovascular system based on stochastic simulation of a one dimensional arterial network. A general analysis of different uncertainties and probability characteriza ...

Implicit coupling of one-dimensional and three-dimensional blood flow models with compliant vessels

Alfio Quarteroni, Simone Deparis, Adelmo Cristiano Innocenza Malossi, Paolo Crosetto

Simulating arterial trees in the cardiovascular system can be made by the help of different models, depending on the outputs of interest and the desired degree of accuracy. In particular, one-dimensional fluid-structure interaction models for arteries are ...

On the physical consistency between three-dimensional and one-dimensional models in haemodynamics

Alfio Quarteroni, Christian Vergara, Luca Formaggia

In this work we discuss the reliability of the coupling among three-dimensional (3D) and one-dimensional (1D) models that describe blood flowing into the circulatory tree. In particular, we study the physical consistency of the 1D model with respect to the ...

Photoreduction of CO2 Using [Ru(bpy)2(CO)L]n+ Catalysts in Biphasic Solution/Supercritical CO2 Systems

Hubert Girault, Manuel Alejandro Méndez Agudelo, Kathryn Ellen Toghill, Patrick Voyame

The photosensitized reduction of carbon dioxide by the molecular catalyst [Ru(bpy)2(CO)L] is studied in a biphasic liquid-condensed gas system. Increasing pressure is shown to enhance the initial production rate and turnover number of the catalyst before d ...
