The functional impact of myofiber macroscopic organization and disarray in computational models of the murine heart
Carlo Guastamacchia, Roberto Piersanti, Francesco Giardini +5
A major challenge in computational models of cardiac electromechanics is the reconstruction of myocardial fiber architecture, as direct in vivo measurements of fiber orientation ar…

Coupled Eikonal problems to model cardiac reentries in Purkinje network and myocardium
Samuele Brunati, Michele Bucelli, Roberto Piersanti +2
We propose a novel partitioned scheme based on Eikonal equations to model the coupled propagation of the electrical signal in the His-Purkinje system and in the myocardium for card…

Defining myocardial fiber bundle architecture in atrial digital twins
Roberto Piersanti, Ryan Bradley, Syed Yusuf Alid +3
A key component in developing atrial digital twins (ADT) - virtual representations of patients' atria - is the accurate prescription of myocardial fibers which are essential for th…
