Finding information-rich electrocardiographic biomarkers to characterize atrial fibrillation.

Atrial fibrillation (AF) is the most common cardiac arrhythmia; it will affect one in four adults worldwide in their lifetime. AF has serious consequences, including drastically increased risk of stroke. Catheter ablation surgery is an established treatmen ...

Analysis of morphological and hemodynamical indexes in abdominal aortic aneurysms as preliminary indicators of intraluminal thrombus deposition

Alfio Quarteroni, Simone Deparis, Claudia Maria Colciago

In this paper, we study the correlation between the wall shear stress, a hemodynamical index derived from numerical simulations, and an new index MFA-ILT for the characterization of intraluminal thrombus (ILT) in the presence of abdominal aortic aneurysms. ...

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 ...

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 ...

Flutter Suppression of a Bridge Section Model Endowed with Actively Controlled Flap Arrays

Alcherio Martinoli, Klara Maria Boberg, Glauco Feltrin

In this work, we investigate active flutter control of a bridge section model equipped with arrays of flaps. We consider three simple control algorithms based on an amplitudegain and a phase-shift for actuating the flaps and stabilizing the section model. ...

Impact of Conduction Velocity on Local Capture of Atrial Fibrillation Induced by Rapid Pacing

Jean-Marc Vesin, Adrian Luca, Alexandru Rusu

Objectives: Rapid pacing of atrial fibrillation (AF) can induce local atrial capture. The present model-based study investigated the impact of atrial tissue conduction velocity on AF capture ability during rapid septal pacing. Methods: The AF model combine ...

Correlation Dimension as a Measure of the Atrial Fibrillation Capture during Atrial Septal Pacing

Jean-Marc Vesin, Adrian Luca

In the present model-based study, the correlation dimension (D2) was used as a measure of the effectiveness of atrial septal pacing during atrial fibrillation (AF). From ongoing simulated atrial fibrillation, instantaneous transmembrane potential maps were ...

Bioluminescent sensor proteins for point-of-care therapeutic drug monitoring

Rudolf Griss

To ensure efficacy but avoid toxicity, many drugs require monitoring of their concentrations in the patient’s blood during therapy. Currently, therapeutic drug monitoring (TDM) is done in diagnostic laboratories that need trained personnel and expensive in ...

Measures of Right Atrial Organization as a Mean to Select Candidates for Sinus Rhythm Restoration by Catheter Ablation

Jean-Marc Vesin, Andréa Buttu, Etienne Pruvot

Stepwise catheter ablation (step-CA) can terminate long-standing persistent atrial fibrillation (LS-pAF) within the left atrium (LA) or may require additional right atrial (RA) ablation. Intracardiac organization indices such as AF cycle length (AFCL) have ...
