Fast characterization of inducible regions of atrial fibrillation models with multi-fidelity Gaussian process classification [PDF]

open access: yesarXiv, 2021
Computational models of atrial fibrillation have successfully been used to predict optimal ablation sites. A critical step to assess the effect of an ablation pattern is to pace the model from different, potentially random, locations to determine whether arrhythmias can be induced in the atria.

FIBRILAÇÃO ATRIAL COMO FATOR DE RISCO PARA AVC: ABORDAGENS CLÍNICAS E TRATAMENTO

open access: yesBrazilian Journal of Implantology and Health Sciences
A fibrilação atrial (FA) é uma arritmia cardíaca comum que aumenta o risco de acidente vascular cerebral (AVC) devido à formação de coágulos que podem obstruir vasos cerebrais.

A Survey of Pathways for Mechano-Electric Coupling in the Atria [PDF]

open access: yesarXiv, 2020
Mechano-electric coupling (MEC) in atrial tissue has received sparse investigation to date, despite the well-known association between chronic atrial dilation and atrial fibrillation (AF). Of note, no fewer than six different mechanisms pertaining to stretch-activated channels, cellular capacitance and geometric effects have been identified in the ...

Fully Automatic Segmentation and Objective Assessment of Atrial Scars for Longstanding Persistent Atrial Fibrillation Patients Using Late Gadolinium-Enhanced MRI [PDF]

open access: yes, 2017
Purpose: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is correlated with increased morbidity and mortality. It is associated with atrial fibrosis, which may be assessed non-invasively using late gadolinium-enhanced (LGE) magnetic resonance imaging (MRI) where scar tissue is visualised as a region of signal enhancement.

Influence of the flow split ratio on the position of the main atrial vortex: implications for stasis on the left atrial appendage [PDF]

open access: yesComput.Biol.Med.(2024),178:108772
Background: Despite the recent advances in computational fluid dynamics (CFD) techniques applied to blood flow within the left atrium (LA), the relationship between atrial geometry, flow patterns, and blood stasis within the left atrial appendage (LAA) remains unclear.

Graph-Time Spectral Analysis for Atrial Fibrillation [PDF]

open access: yesarXiv, 2019
Atrial fibrillation is a clinical arrhythmia with multifactorial mechanisms still unresolved. Time-frequency analysis of epicardial electrograms has been investigated to study atrial fibrillation. However, deeper understanding of atrial fibrillation can be achieved if the spatial dimension can be incorporated.
