Electrophysiological characteristics of permanent atrial fibrillation: insights from research models of cardiac remodeling

Climent, A.M.; Guillem Sánchez, María Salud; Atienza Fernández, Felipe; Fernandez-Aviles, F. (Expert Reviews (formerly Future Drugs), 2014-11-29)

[EN] Atrial fibrillation (AF) results in a remodeling of the electrical and structural characteristics of the cardiac tissue which dramatically reduces the efficacy of pharmacological and catheter-based ablation therapies. ...
Frontiers in Non-invasive Cardiac Mapping: Rotors in Atrial Fibrillation-Body Surface Frequency-Phase Mapping

Atienza, F.; Climent, A.M.; Guillem Sánchez, María Salud; Berenfeld, O. (WB Saunders, 2015-03)

[EN] Experimental and clinical data demonstrate that atrial fibrillation (AF) maintenance in animals and groups of patients depends on localized reentrant sources localized primarily to the pulmonary veins (PVs) and the ...
Identification of Dominant Excitation Patterns and Sources of Atrial Fibrillation by Causality Analysis

Rodrigo Bort, Miguel; Climent, A.M.; Liberos Mascarell, Alejandro; Calvo, D.; Fernandez-Aviles, F.; Berenfeld, O.; Atienza, F.; Guillem, M.S (Springer Verlag (Germany), 2016-08)

Burden of atrial fibrillation (AF) can be reduced by ablation of sources of electrical impulses driving AF but driver identification is still challenging. This study presents a new methodology based on causality analysis ...
Regularization Techniques for ECG Imaging during Atrial Fibrillation: A Computational Study

Figuera C; Suárez Gutiérrez V; Hernández-Romero, Ismael; Rodrigo Bort, Miguel; Liberos Mascarell, Alejandro; Atienza, F.; Guillem Sánchez, María Salud; Barquero-Pérez O; Climent, A.M.; Alonso Atienza, Felipe (Frontiers Media, 2016-10-14)

The inverse problem of electrocardiography is usually analyzed during stationary rhythms. However, the performance of the regularization methods under fibrillatory conditions has not been fully studied. In this work, we ...
Role of atrial tissue remodeling on rotor dynamics an in vitro study

Climent, A.M.; Guillem Sánchez, María Salud; Fuentes, L.; Lee, P.; Bollensdorff, C.; Fernandez-Santos, M.E.; Suarez-Sancho, S.; Sanz-Ruiz, R.; Sanchez, P.L.; Atienza, F.; Fernandez-Aviles, F. (American Physiological Society, 2015-12-01)

The objective of this article is to present an in vitro model of atrial cardiac tissue that could serve to study the mechanisms of remodeling related to atrial fibrillation (AF). We analyze the modification on gene expression ...
