A Variable Stiffness Catheter Controlled with an External Magnetic Field

Remote magnetic navigation of catheters is a technique used to perform radiofrequency ablation of heart tissue in order to treat cardiac arrhythmias. The flexible magnetic catheters used in this context are in some cases not sufficiently dexterous to navig ...

Thin films for Healthcare Acquired Infections (HAIs) prevention

Sami Rtimi

This thesis addresses the preparation of antibacterial surfaces for hospital facilities taking biomedical thin polymer films, textiles and catheter as probes. Magnetron sputtering is used to apply the coatings leading to fast bacterial inactivation in the ...

In Vitro and In Vivo Effectiveness of an Innovative Silver-Copper Nanoparticle Coating of Catheters To Prevent Methicillin-Resistant Staphylococcus aureus Infection

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

In this study, silver/copper (Ag/Cu)-coated catheters were investigated for their efficacy in preventing methicillin-resistant Staphylococcus aureus (MRSA) infection in vitro and in vivo. Ag and Cu were sputtered (67/33% atomic ratio) on polyurethane cathe ...

Experimental Testing of AF Septal Modeling Results

Adrian Luca

Introduction: Moving to clinical validation is an essential phase with every model-based result. However, this translation is often not straightforward because animal models differ from human computer models in many anatomic and electrophysiologic ways, wh ...

Metal artefact reduction in computed tomography images by a fourth-order total variation flow

Alfio Quarteroni, Elena Faggiano

Permanent metallic implants, such as dental fillings and cardiac devices, generate streaks-like artefacts in computed tomography (CT) images. In this article, we propose a strategy to perform metal artefact reduction (MAR) that relies on the total variatio ...

Nonlinear analysis of right atrial electrograms predicts termination of persistent atrial fibrillation within the left atrium by catheter ablation

Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot

The termination of long-standing persistent atrial fibrillation (LS-pAF) can be achieved by stepwise catheter ablation (step-CA) within the left atrium (LA). Our study aims to applying complexity measures derived from nonlinear time series analysis in orde ...

Prediction of Atrial Fibrillation Termination by Catheter Ablation Using Adaptive Frequency Tracking of Atrial ECG Signal

Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot

Our study aims at determining whether the efficiency of step-wise catheter ablation (step-CA) of persistent atrial fibrillation (pAF) can be tracked using organization indices based on the harmonic components of atrial ECG signals until pAF termination. EC ...

Divergent patterns of atrial ECG organization during catheter ablation of persistent atrial fibrillation revealed by adaptive harmonic frequency schemes

Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot

Introduction: We hypothesized that organization indices based on the analysis of atrial ECG harmonic components may help identify patients (pts) with persistent AF (pAF) unresponsive to pulmonary vein isolation (PVI) and left atrial (LA) ablation. Using ad ...

Isogeometric Analysis of Electrophysiological Models on Surfaces

Alessandro Samuele Patelli

In this project we numerically simulate electrophysiological models for cardiac applications by means of Isogeometric Analysis. Specifically, we aim at understanding the advantages of using high order continuous NURBS (Non-UniformRational B-Splines) basis ...
