    Background. Voltage mapping allows identifying the arrhythmogenic substrate during scar-related ventricular arrhythmia (VA) ablation procedures. Slow conducting channels (SCCs), defined by the presence of electrogram (EGM) ...
  • Lluch Alvarez, Èric; De Craene, Mathieu; Bijnens, Bart; Sermesant, Maxime; Noailly, Jérôme; Camara, Oscar; Morales, Hernán G. (Springer, 2019)
    Cardiac modeling has recently emerged as a promising tool to study pathophysiology mechanisms and to predict treatment outcomes for personalized clinical decision support. Nevertheless, achieving convergence under large ...
  • Romero García, Daniel (Universitat Pompeu Fabra, 2016-01-18)
    The usability of computer models of the heart depends mostly on their capacity to accurately represent heart anatomy, microstructure and function. However, integrating such a variety of biological data is often not possible. ...
  • Doste Beltrán, Rubén (Universitat Pompeu Fabra, 2019-11-18)
    The purpose of this thesis was to develop personalised cardiovascular therapy guided by multimodal noninvasive imaging and simulations, combined with artificial intelligence tools, for the management of the outflow tract ...
  • Soto-Iglesias, David (Universitat Pompeu Fabra, 2016-09-13)
    The development of novel technologies is allowing a complete description of the heart structure and function, including geometrical, myocardial tissue viability and electrical activation information. The joint analysis of ...

    The electrical activation of the heart is a complex physiological process that is essential for the understanding of several cardiac dysfunctions, such as ventricular tachycardia (VT). Nowadays, electro-anatomical mappings ...
  • Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Alarcón, Francisco; Caixal, Gala; Mont, Lluís; Camara, Oscar; Butakoff, Constantine (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Two-dimensional representation of 3D anatomical structures is a simple and intuitive way for analysing patient information across populations and image modalities. While cardiac ventricles, especially the left ventricle, ...
  • Lluc Álvarez, Èric (Universitat Pompeu Fabra, 2019-10-21)
    The functioning of the heart, which main role is pumping blood to the rest of the body, is the result of a complex combination of multi-scale physical processes from the molecular to the tissue level. The predominance of ...
