Harmonic frequency tracking algorithm for predicting the success of pharmacological cardioversion of atrial fibrillation

Jean-Marc Vesin, Laurent Renaud Uldry, Andréa Buttu, Jérôme Sébastien Van Zaen, Lukas Kappenberger

Purpose: Non-invasively predicting the success of pharmacological cardioversion for patients with atrial fibrillation (AF) would be of great interest in clinical settings. In this study, an adaptive algorithm for tracking fundamental and harmonic component ...

Cardiac ablation, How Contact Force influences lesion quality

Olivier Frémont

Cardiac ablation is a worldwide accepted minimally invasive procedure to treat Atrial Fibrillation (AF). It consists in creating lesions with a catheter in the cardiac tissue in order to cut off specific electrical pathways. During this project, based on p ...

Susceptibility to Paroxysmal Atrial Fibrillation: A Study using Sinus Rhythm P Wave Parameters

Jean-Marc Vesin, Lam Dang, Lukas Kappenberger

Early recognition of patients at high risk for atrial fibrillation may help to minimize potential health risks. The detection of susceptibility to develop atrial fibrillation is thus a real clinical challenge. Whereas many studies have used the signal-aver ...

Biomechanical, morphological and zero-stress state characterization of jugular vein remodeling in arteriovenous fistulas for hemodialysis

Nikolaos Stergiopoulos

While the role of hemodynamic variables on the development of intimal hyperplasia in arteriovenous fistulas for hemodialysis has been examined, less is known about the intramural biomechanical factors. In this study, arteriovenous fistulas were created by ...

Optimizing local capture of atrial fibrillation: a model based study of the influence of tissue dynamics on the outcome of rapid pacing

Jean-Marc Vesin, Laurent Renaud Uldry

While successful termination by pacing of organized atrial tachycardias has been observed in patients, rapid pacing of AF can induce a local capture of the atrial tissue but in general no termination. The purpose of this study was to perform a systematic e ...

Decreased Excitability as a Protective Mechanism Against Repolarization Alternans-Induced Atrial Reentry

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: We recently observed in human left atrium periods of intermittent 2:1 and 1:1 atrial capture, preceded by atrial repolarization alternans (Re-ALT) during rapid pacing. It remains undetermined whether Re- ALT plays a role in preventing 1:1 atr ...

Spatial and temporal variability of snow depth and SWE in a small mountain catchment

Michael Lehning, Thomas Grünewald

The spatio-temporal variability of the mountain snow cover determines the avalanche danger, snow water storage, permafrost distribution and the local distribution of fauna and flora. Using a new type of terrestrial laser scanner (TLS), which is particularl ...

Spontaneous termination of atrial fibrillation: study of the effect of atrial geometry in a biophysical model

Jean-Marc Vesin, Laurent Renaud Uldry, Vincent Jacquemet, Lukas Kappenberger

We studied the mechanisms of spontaneous termination of atrial fibrillation in a biophysical model of human atria, during the eight seconds preceding termination. The earliest detectable changes in the cycle length and the number of wavefronts occurred abo ...

Melanocyte-like cells in the heart and pulmonary veins contribute to atrial arrhythmia triggers

Friedrich Beermann, Fang Liu

Atrial fibrillation is the most common clinical cardiac arrhythmia. It is often initiated by ectopic beats arising from the pulmonary veins and atrium, but the source and mechanism of these beats remains unclear. The melanin synthesis enzyme dopachrome tau ...
