Hemodynamic effects of a dielectric elastomer augmented aorta on aortic wave intensity: An in-vivo study

Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Francesco Clavica, Armando Matthieu Walter, Silje Ekroll Jahren, Lorenzo Ferrari

Dielectric elastomer actuator augmented aorta (DEA) represents a novel approach with high potential for assisting a failing heart. The soft tubular device replaces a section of the aorta and increases its diameter when activated. The hemodynamic interactio ...

An image-based computational hemodynamics study of the Systolic Anterior Motion of the mitral valve

Alfio Quarteroni, Luca Dede', Christian Vergara, Marco Fedele

Systolic Anterior Motion (SAM) of the mitral valve - often associated with Hypertrophic Obstructive Cardiomyopathy (HOCM) - is a cardiac pathology in which a functional subaortic stenosis is induced during systole by the mitral leaflets partially obstructi ...

Glutathione deficit affects the integrity and function of the fimbria/fornix and anterior commissure in mice: relevance for schizophrenia

Rolf Gruetter, Yohan Van de Looij, Kim Do, Alberto Corcoba, Aline Monin, João Miguel das Neves Duarte

BACKGROUND: Structural anomalies of white matter (WM) are found in various brain regions of patients with schizophrenia, bipolar and other psychiatric disorders, but the causes at cellular and molecular levels remain unclear. Oxidative stress and redox dys ...

Off-the-shelf human decellularized tissue-engineered heart valves in a non-human primate model

Peter Modregger, Marco Stampanoni, Chad Brokopp

Heart valve tissue engineering based on decellularized xenogenic or allogenic starter matrices has shown promising first clinical results. However, the availability of healthy homologous donor valves is limited and xenogenic materials are associated with i ...

Partitioned Solution of Geometrical Multiscale Problems for the Cardiovascular System : Models, Algorithms, and Applications

Adelmo Cristiano Innocenza Malossi

The aim of this work is the development of a geometrical multiscale framework for the simulation of the human cardiovascular system under either physiological or pathological conditions. More precisely, we devise numerical algorithms for the partitioned so ...

Mechano-electrical contribution of ventricular contractions to the complexity of atrial fibrillation electrograms

Jean-Marc Vesin, Andréa Buttu, Etienne Pruvot, Sarah Volorio

Purpose: Intracardiac organization indices (OI) have been used to track the efficiency of stepwise radiofrequency catheter ablation (step-CA) of persistent atrial fibrillation (pers-AF). A better understanding of the components and complexity of AF electro ...

Engineering of living autologous human umbilical cord cell-based septal occluder membranes using composite PGA-P4HB matrices

Peter Modregger, Marco Stampanoni

Interventional closure of intracardiac wall defects using occluder devices has evolved as a highly attractive treatment option. However, incomplete and delayed healing reactions often result in a major risk of residual defects, thromboembolism, or device f ...

Intrinsic defect complexes in CdTe and ZnTe

Alexandra Sarabando de Carvalho

Radiation defects in CdTe and ZnTe are modeled from first principles. The most important intrinsic defects resulting from cation evaporation or displacement are cation vacancies and tellurium anti-sites, electrically active defects characterized by a low f ...

The non-circular shape of FloWatch®-PAB prevents the need for pulmonary artery reconstruction after banding

Alfio Quarteroni, Paolo Zunino, Ludwig Von Segesser

To evaluate the differences between non-circular shape of FloWatch®-PAB and conventional pulmonary artery (PA) banding. Methods: Geometrical analysis. Conventional banding and FloWatch®-PAB perimeters were plotted against cross-sections. Computational flui ...

Essential role of endothelial Notch1 in angiogenesis

Freddy Radtke

BACKGROUND: Notch signaling influences binary cell fate decisions in a variety of tissues. The Notch1 receptor is widely expressed during embryogenesis and is essential for embryonic development. Loss of global Notch1 function results in early embryonic le ...
