Book ChapterDOI
Modeling atrial fiber orientation in patient-specific geometries: a semi-automatic rule-based approach
Martin W. Krueger,Viktor Schmidt,Catalina Tobón,Frank Weber,Cristian Lorenz,D. U. J. Keller,Hans Barschdorf,Michael Burdumy,Peter F. Neher,Gernot Plank,Kawal Rhode,Gunnar Seemann,Damien Sanchez-Quintana,Javier Saiz,Reza Razavi,Olaf Dössel +15 more
TL;DR: A novel robust semi-automatic method to incorporate atrial anisotropy and heterogeneities into patient-specific models is introduced, an important step towards creating realistic patient- specific atrial models for clinical applications.
Journal ArticleDOI
A Three-Dimensional Human Atrial Model with Fiber Orientation. Electrograms and Arrhythmic Activation Patterns Relationship
Catalina Tobón,Carlos A. Ruiz-Villa,Carlos A. Ruiz-Villa,Elvio Heidenreich,Lucia Romero,F. Hornero,Javier Saiz +6 more
TL;DR: The model is the first human atrial model with realistic fiber orientation used to investigate the relationship between different atrial arrhythmic propagation patterns and the electrograms observed at more than 43000 points on the atrial surface.
Journal ArticleDOI
Dynamic Approximate Entropy Electroanatomic Maps Detect Rotors in a Simulated Atrial Fibrillation Model
Juan P. Ugarte,Andrés Orozco-Duque,Catalina Tobón,Vaclav Kremen,Daniel Novák,Javier Saiz,Tobias Oesterlein,Clauss Schmitt,Armin Luik,John Bustamante +9 more
TL;DR: The results suggest that high approximate entropy values are able to detect a high level of fractionation and to locate rotor tips in simulated atrial fibrillation episodes, and suggest that dynamic approximate entropy maps could become a tool for atrialfibrillation rotor mapping.
Journal ArticleDOI
The relative role of refractoriness and source-sink relationship in reentry generation during simulated acute ischemia.
TL;DR: The mismatch of the source–sink relationship, rather than solely refractoriness, was the ultimate cause of the UDB leading to reentry, and the SF represents a very powerful tool to study the mechanisms responsible for reentry.
Journal ArticleDOI
Dominant frequency and organization index maps in a realistic three-dimensional computational model of atrial fibrillation.
TL;DR: In this article, the spectral characteristics of different patterns of atrial fibrillation (AF) at high spatial resolution have been studied using simulation, using a realistic 3D model of the human atria.
