STAR locally prolongs effective refractory period and increases ventricular tachycardia cycle length without short-term scar formation or functional decline: Insights from a translational porcine model study

This dataset contains data required to reproduce computational simulations presented in the 2025 paper by Zenger et al. This data set comprises (1) Geometric descriptions of the simulation domain (whole heart, tissue wedge, etc.), with point clouds interconnected by finite elements, each of which is associated with a vector encoding local myofiber orientation. (2) Parameter files describing functional cell- and tissue-scale properties of different tissue regions, perturbations to be applied to the model during the simulation (e.g., electrical stimuli), and numerical solver settings. (3) Initial condition state files describing the functional state of the model at the beginning of the simulation, if these conditions differ from the cell-scale default parameters. All of the above are stored in plain text or binary formats compatible with the openCARP framework, which is freely available for non-commercial use., , # STAR locally prolongs effective refractory period and increases ventricular tachycardia cycle length without short-term scar formation or functional decline: Insights from a translational porcine model study

#### Description of the data and file structure

The repository contains all finite element model files needed to rerun simulations in openCARP. These files have the basename ring_hemi_26mm. or ring_hemi_28mm.*, depending on model dimensions.

Specific finite element mesh file types:

.pts: description of points in Cartesian coordinates (spacial unit: microns)
.elem: description of how nodes (zero indexed) are interconnected by elements
.lon: fiber orientations for each element
.surf: description of mesh surface (zero ind...,
