Project Details

Description

An in silico study is proposed to evaluate the impact of the spatial resolution of basket-type multielectrode catheters in the characterization of atrial fibrillation patterns and their ablation. For this, mathematical models of atrial electrophysiology in fibrillatory conditions will be implemented, EGMs will be calculated using virtual catheters with different spatial resolutions in simulated AF episodes, and ablation patterns guided by EGM processing will be applied. Electrophysiological computational models allow control of fibrillatory propagation conditions, which will be used to study how the spatial resolution of basket-type multielectrode catheters affects the characterization of atrial electrical dynamics for the identification of sites susceptible to ablation. This project is focused on in the third SDG "Health and Well-being", in the UDEM research line "Modeling and simulation of physiological systems", and in Challenge 1 for the Fourth Industrial Revolution "Applications of biomodeling in Health", within the Sciences thematic line of Materials and Biomodeling of the Faculty of Basic Sciences.

Objective

To evaluate the impact of the spatial resolution of multielectrode basket-type catheters in the characterization of ablatable substrates for the treatment of persistent atrial fibrillation, using computational models.

Expected results

To answer the research question, how does the spatial resolution of basket-type multielectrode catheters affect the characterization of atrial electrical dynamics for the identification of sites susceptible to ablation?
