Feasibility of a Dielectric Elastomer Augmented Aorta

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne, Francesco Clavica, Morgan Almanza, David Moser

Although heart transplantation is a gold standard for severe heart failure, there is a need for alternative effective therapies. A dielectric‐elastomer aorta is used to augment the physiological role of the aorta in the human circulatory system. To this en ...

Increasing heart vascularisation after myocardial infarction using brain natriuretic peptide stimulation of endothelial and WT1(+) epicardial cells

Na Li, Alexia Laurie Carboni

Brain natriuretic peptide (BNP) treatment increases heart function and decreases heart dilation after myocardial infarction (MI). Here, we investigated whether part of the cardioprotective effect of BNP in infarcted hearts related to improved neovascularis ...

Experimental study of atrial fibrillation cycle length during rapid atrial septal pacing

Jean-Marc Vesin, Adrian Luca, Sasan Yazdani

Computer model-based simulations have shown that rapid stimulation at 60-100% of atrial fibrillation cycle length (AFCL) from a ring of electrodes located around the septum may induce local capture in both atria for most AF dynamics. The present study aims ...

Numerical modeling of heart valves using resistive Eulerian surfaces

Alfio Quarteroni, Aymen Laadhari

The goal of this work is the development and numerical implementation of a mathematical model describing the functioning of heart valves. To couple the pulsatile blood flow with a highly deformable thin structure (the valve's leaflets), a resistive Euleria ...

Helical flows and asymmetry of blood jet in dilated ascending aorta with normally functioning bicuspid valve

Alfio Quarteroni, Christian Vergara, Elena Faggiano

Bicuspid aortic valve (BAV) is associated with aortic dilatation and aneurysm. Several studies evidenced an eccentric systolic flow in ascending aorta associated with increased wall shear stresses (WSS) and the occurrence of an helical systolic flow. This ...

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 ...
