Are Coronary Sinus Features Reflecting the Effect of Catheter Ablation of Atrial Fibrillation as P-waves Do?

Vraka, Aikaterini; Bertomeu-González, Vicente; Hornenro, Fernando; Langley, Philip; Alcaraz, Raúl; Rieta, J J (IEEE, 2021-11-19)

[EN] Atrial substrate alteration due to catheter ablation (CA) of atrial fibrillation (AF) is primarily assessed from P-waves. Nonetheless, how CA affects critical structures is ignored. The aim of the current study is to ...
Characterization of the Substrate Modification in Patients Undergoing Catheter Ablation of Atrial Fibrillation

Vraka, Aikaterini (Universitat Politècnica de València, 2023-01-20)

[ES] La fibrilación auricular (FA) es la arritmia cardíaca más común. A pesar de la gran popularidad de la ablación con catéter (AC) como tratamiento principal, todavía hay margen de mejora. Aunque las venas pulmonares ...
Parallel Study on Surface and Invasive Recordings Across Catheter Ablation Steps of Paroxysmal Atrial Fibrillation

Vraka, Aikaterini; Hornero, Fernando; Quesada, Aurelio; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (IEEE, 2021-11-19)

[EN] Catheter ablation (CA) is the star treatment of atrial fibrillation (AF). However, important issues regarding its procedure have only been superficially explored. While universal CA effect is assessed, the role of ...
Reliable Paroxysmal Atrial Fibrillation Substrate Assessment During Sinus Rhythm Through Optimal Estimation of Local Activation Waves Dynamics

Vraka, Aikaterini; Hornero, Fernando; Quesada, Aurelio; Faes, Luca; Alcaraz, Raúl; Rieta, J J (IEEE, 2020-10-30)

[EN] The analysis of coronary sinus (CS) electrograms (EGMs) during catheter ablation (CA) of atrial fibrillation (AF) is highly important for AF substrate evaluation. However, channels of the CS catheter may be affected ...
Study on How Catheter Ablation Affects Atrial Structures in Patients with Paroxysmal Atrial Fibrillation: The Case of the Coronary Sinus

Vraka, Aikaterini; Bertomeu-González, Vicente; Osca, Joaquín; Ravelli, Flavia; Alcaraz, Raúl; Rieta, J J (IEEE, 2020-10-30)

[EN] It has been shown that substrate modification due to catheter ablation (CA), the first-line treatment of paroxysmal atrial fibrillation (PAF), provokes alterations in P-wave features of the surface electrocardiogram. ...
The Dissimilar Impact in Atrial Substrate Modification of Left and Right Pulmonary Veins Isolation after Catheter Ablation of Paroxysmal Atrial Fibrillation

Vraka, Aikaterini; Bertomeu-González, Vicente; Fácila, Lorenzo; Moreno-Arribas, José; Alcaraz, Raul; Rieta, J J (MDPI AG, 2022-03)

[EN] Since the discovery of pulmonary veins (PVs) as foci of atrial fibrillation (AF), the commonest cardiac arrhythmia, investigation revolves around PVs catheter ablation (CA) results. Notwith-standing, CA process itself ...
The Relevance of Heart Rate Fluctuation When Evaluating Atrial Substrate Electrical Features in Catheter Ablation of Paroxysmal Atrial Fibrillation

Vraka, Aikaterini; Moreno-Arribas, José; Gracia-Baena, Juan M.; Hornero, Fernando; Alcaraz, Raúl; Rieta, J J (MDPI AG, 2022-06-01)

[EN] Coronary sinus (CS) catheterization is critical during catheter ablation (CA) of atrial fibrillation (AF). However, the association of CS electrical activity with atrial substrate modification has been barely investigated ...
Thermal impact of balloon occlusion of the coronary sinus during mitral isthmus radiofrequency ablation: an in-silico study

González-Suárez, Ana; d'Avila, Andre; Pérez, Juan J; Reddy, Vivek Y.; Cámara, Óscar; Berjano, Enrique (Taylor & Francis, 2019-01-01)
