The V-Heart network includes practically all the Spanish groups that investigate the computational modeling of the heart. In the network we can find specialized groups in the physiological modeling of electrical activity, from the cellular level to the level of the human body. In addition, the network consists of groups specialized in modeling the mechanical activity and specialized groups in interpreting signals at different levels. It also consists of experts in numerical methods that will facilitate both the development of the models and the implementation of software that allows simulations to be carried out in acceptable times for medical professionals and high-performance computer experts who make the environment available to the Alya network developed at the Barcelona Supercomputing Center (BSC) for the implementation of cardiac computer models.

The V-Heart network is, therefore, a multidisciplinary network that will allow dealing with the complex problems associated with the development of multi-scale models of the heart.

It is important to emphasize that the development of these models, especially those oriented to personalized medicine, will require the collaboration of medical teams that can support the network with the provision of information and the subsequent validation of these models. Members of the V-Heart network have extensive experience in collaboration with medical teams.
The network considers it essential to promote the involvement of private companies both in the support of research and in the development of products based on the research that will be carried out within the framework of the network.

The main characteristics of the groups that are members of the network are briefly described below.

Ci2B

(Centro de Investigación e Innovación en Bioingeniería, Universitat Politècnica de València ) is a research center with more than 20 years of experience in the development of multi-scale models of the heart. The Ci2B has published models of the electrical activity of different cardiac tissues (atrium, ventricle or purkinje fibers). In recent years he has developed methods for the study of cardiotoxicity of drugs and therapies based on radiofrequency ablation based on realistic 3D models of the ventricles and the atria.

BIOFIS-UNAV

More information Presentation UNAV

(Grupo de Biofísica del corazón) is a research group that works on modeling cardiac tissue at different scales. He has been dedicated to this topic for more than 10 years and as an important achievement he has developed numerical methods to study the process of cardiac fibrillation and defibrillation. The goal is to obtain a less invasive defibrillator (low energy).

BIOCOM-SC

 

(Grupo de Biología Computacional y sistemas complejos) is a research group in computational modeling of biological systems. One of the
main research topics is the modeling of cardiac dynamics, and the mechanisms that give rise to atrial fibrillation. Our models range from the subcellular level, including intracellular calcium dynamics and excitation-contraction coupling, to the level of electrical propagation in tissue and re-entry generation mechanisms, for example fibrosis or dynamic instabilities.
