A single-beat algorithm to discriminate farfield from nearfield bipolar voltage electrograms from the pulmonary veins

Jean-Marc Vesin, Adrian Luca, Vincent Schlageter

Background Superimposition of farfield (FF) and nearfield (NF) bipolar voltage electrograms (BVE) complicates the confirmation of pulmonary vein (PV) isolation after catheter ablation of atrial fibrillation. Our aim was to develop an automatic algorithm ba ...

Computational Analysis of Turbulent Hemodynamics in Radiocephalic Arteriovenous Fistulas to Determine the Best Anastomotic Angles

Alfio Quarteroni, Christian Vergara

Background: Hemodynamics has been known to play a major role in the development of intimal hyperplasia leading to arteriovenous fistula failure. The goal of our study is to investigate the influence of different angles of side-to-end radiocephalic anastomo ...

Renal metabolism of hyperpolarized [1-13C]aspartate

Hikari Ananda Infinity Yoshihara

Aspartic acid is involved in several central metabolic pathways, including gluconeogenesis, the urea cycle, de novo nucleotide synthesis, the malate-aspartate shuttle, and via transmination the TCA cycle. The conversion in vivo of hyperpolarized [1-13C]pyr ...

Laue micro-diffraction and crystal plasticity finite element simulations to reveal a vein structure in fatigued Cu

Helena Van Swygenhoven, Nicolò Grilli, Ainara Irastorza Landa

The formation of a vein during cyclic shearing of a single copper crystal oriented for single slip can be followed in transmission Laue diffraction by analyzing the spatially resolved lattice rotation evolution. Because Laue transmission integrates the sig ...

A computational fluid-structure interaction analysis of coronary Y-grafts

Alfio Quarteroni, Christian Vergara

Coronary artery disease is one of the leading causes of death worldwide. The stenotic coronary vessels are generally treated with coronary artery bypass grafts (CABGs), which can be either arterial (internal mammary artery, radial artery) or venous (saphen ...

Influence of Right and Left Atrial Tissue Heterogeneity on Atrial Fibrillation Perpetuation

Jean-Marc Vesin, Adrian Luca, Vincent Jacquemet

We propose a biophysical modelling approach to separately investigate the impact of right and left atrial (RA/LA) electrical heterogeneity on atrial fibrillation (AF) perpetuation. The baseline AF substrate was based on a 4:1 anisotropy ratio and uniform m ...

Living-Engineered Valves for Transcatheter Venous Valve Repair

Peter Modregger, Marco Stampanoni

Background: Chronic venous insufficiency (CVI) represents a major global health problem with increasing prevalence and morbidity. CVI is due to an incompetence of the venous valves, which causes venous reflux and distal venous hypertension. Several studies ...

Linearizability Is Not Always a Safety Property

Rachid Guerraoui, Eric Ruppert

We show that, in contrast to the general belief in the distributed computing community, linearizability, the celebrated consistency property, is not always a safety property. More specifically, we give an object for which it is possible to have an infinite ...

Prevention of Caval Collapse During Venous Drainage for CPB

Julien Favre

A new plastic self-expanding Smartcanula (Smartcanula LLC, Lausanne, Switzerland) is designed for central insertion and prevention of caval collapse. The objective of our work is to assess the influence of the new design on atrial chatter. Caval collapse o ...

Local hemodynamics and intimal hyperplasia at the venous side of a porcine arteriovenous shunt

Nikolaos Stergiopoulos

Venous anastomotic intimal hyperplasia (IH) observed in the arteriovenous shunt (AVS) has been associated with disturbed hemodynamics. This study aims to correlate hemodynamics with wall histology and wall mechanics by examining the flow field in AVS with ...
