A Three-Dimensional Model of the Human Atria With Heterogeneous Wall Thickness and Fibre Transmurallity - A Realistic Platform for the Study of Atrial Fibrillation

Rocher-Ventura, Sara; Martínez, Laura; López, Alejandro; Ferrer, Ana; Sánchez-Quintana, Damián; Saiz Rodríguez, Francisco Javier (IEEE, 2019-09-11)

[EN] Multiscale cardiac modelling has been increasingly used since it provides a promising framework to improve our understanding of atrial fibrillation physiopathology. In this study, we present a highly detailed ...
Atrial fibrosis identification with unipolar electrogram eigenvalue distribution analysis in multi-electrode arrays

Riccio, Jennifer; Alcaine, Alejandro; Rocher, Sara; Martínez-Mateu, Laura; Saiz Rodríguez, Francisco Javier; Invers-Rubio, Eric; Guillem Sánchez, María Salud; Martínez, Juan Pablo; Laguna, Pablo (Springer-Verlag, 2022-09-13)

[EN] Atrial fibrosis plays a key role in the initiation and progression of atrial fibrillation (AF). Atrial fibrosis is typically identified by a peak-to-peak amplitude of bipolar electrograms (b-EGMs) lower than 0.5 mV, ...
Characterization of Atrial Propagation Patterns and Fibrotic Substrate With a Modified Omnipolar Electrogram Strategy in Multi-Electrode Arrays

Riccio, Jennifer; Alcaine, Alejandro; Rocher-Ventura, Sara; Martínez-Mateu, Laura; Laranjo, Sergio; Saiz Rodríguez, Francisco Javier; Laguna, Pablo; Martínez, Juan Pablo (Frontiers Media SA, 2021-09-03)

[EN] Introduction: The omnipolar electrogram method was recently proposed to try to generate orientation-independent electrograms. It estimates the electric field from the bipolar electrograms of a clique, under the ...
Desarrollo de modelos 3D electrofisiológicos personalizados para el análisis de la influencia de la variabilidad estructural y la fibrosis sobre la actividad eléctrica de la aurícula

López Ruiz, Irene (Universitat Politècnica de València, 2020-10-05)

[ES] El estudio electrofisiológico del corazón es de vital importancia en la prevención, diagnóstico y tratamiento de las enfermedades cardiovasculares. Las simulaciones computacionales de modelos cardiacos permiten realizar ...
Desarrollo de modelos de estiramiento y electromecánicos para evaluar el efecto de la dilatación auricular sobre el establecimiento de la fibrilación auricular

García Vicente, Clara (Universitat Politècnica de València, 2021-09-17)

[ES] Las enfermedades cardiacas conforman la primera causa de muerte en todo el planeta, siendo las arritmias uno de los principales trastornos relacionados con estas patologías. La fibrilación auricular (FA) es conocida ...
Desarrollo de un modelo computacional realista 3D de la aurícula

Rocher Ventura, Sara (Universitat Politècnica de València, 2018-01-09)

[ES] Las enfermedades cardiovasculares son la principal causa de mortalidad en el mundo. Entre las manifestaciones más significativas de las enfermedades cardiovasculares se encuentran las arritmias, relacionadas directamente ...
Estudio, mediante modelos computacionales, del efecto de los cambios estructurales en el tejido en el desarrollo de la fibrilación auricular

Fuster Palop, Javier (Universitat Politècnica de València, 2021-09-13)

[ES] Las enfermedades cardiovasculares son la principal causa de defunción en el mundo. Provocan que cada año mueran más personas como consecuencia de alguna de estas enfermedades que por cualquier otra causa. Entre sus ...
Influence of Gradient and Smoothness of Atrial Wall Thickness on Initiation and Maintenance of Atrial Fibrillation

Azzolin, Luca; Luongo, Giorgio; Rocher-Ventura, Sara; Saiz Rodríguez, Francisco Javier; Dossel, Olaf; Loewe, Axel (IEEE, 2020-09-16)

[EN] This work uses a highly detailed computational model of human atria to investigate the effect of spatial gradient and smoothing of atrial wall thickness on inducibility and maintenance of atrial fibrillation (AF) ...
Omnipolar EGM Voltage Mapping for Atrial Fibrosis Identification Evaluated with an Electrophysiological Model

Riccio, Jennifer; Alcaine, Alejandro; Rocher-Ventura, Sara; Laguna, Pablo; Saiz Rodríguez, Francisco Javier; Martínez, Juan Pablo (IEEE, 2021-01-22)

[EN] Atrial fibrillation (AF) is the most spread heart arrhythmia, whose mechanisms are not completely clear yet. Catheter ablation is a standard treatment, which isolates the area involved in the arrhythmia. Intracardia ...
Putting Oneself in the Body of Others: A Pilot Study on the Efficacy of an Embodied Virtual Reality System to Generate Self-Compassion

Cebolla, Ausias; Herrero, Rocio; Ventura, Sara; Miragall, Marta; Bellosta-Batalla, Miguel; Llorens Rodríguez, Roberto; Baños, Rosa María (Frontiers Media SA, 2019-07-02)

[EN] Compassion-based interventions (CBIs) have been shown to be effective for increasing empathy and compassion, and reducing stress, anxiety, and depression. CBIs are based on constructive meditations where imagery ...
The benchmark framework and exploratory study to investigate the feasibility of 360-degree video-based virtual reality to induce a full body illusion

Ventura, Sara; Cebolla, Ausias; Latorre, Jorge; Escrivá-Martínez, Tamara; Llorens Rodríguez, Roberto; Baños, Rosa (Springer-Verlag, 2022-03)

[EN] The feeling of ownership of a virtual body has been a topic of interest in recent years. In order to observe the mechanisms involved in the perception of the body illusion and its manipulation, the use of virtual ...
Unipolar Electrogram Eigenvalue Distribution Analysis for the Identification of Atrial Fibrosis

Riccio, Jennifer; Rocher-Ventura, Sara; Martínez-Mateu, Laura; Alcaine, Alejandro; Saiz Rodríguez, Francisco Javier; Martínez, Juan Pablo; Laguna, Pablo (IEEE, 2020-09-16)
