We are very proud to announce the publication of a major step forward in our understanding of the relationship between disease-related (fibrotic) remodeling of the heart and biomechanics of atrial contraction. Congratulations to first author Dr. Åshild Telle and thank you to our dear friend and collaborator, co-senior author Dr. Christoph Augustin. This paper is a big deal for our lab for several reasons. First, it include an implementation of fractional factorial design (FFE), a “Design of Experiments” technique Pat spends…

New Research on How Different Fibrotic Patterns Alter Cardiac Tissue Mechanics
We are excited to announce a new CardSS Lab paper, entitled “Mechanical Modeling of Cardiac Fibrosis with Explicit Spatial Representation of Cellular Structure and Collagen Alignment” by Dr. Åshild Telle, Pat, and other collaborators. The study reveals that replacement fibrosis greatly amplifies the level of stress on remaining cells and softens directional stiffness. Interstitial fibrosis, on the other hand, primarily stiffens the tissue stretch without altering anisotropy. The publisher has posted a direct link to a publicly-available PDF version of the…
New Breakthrough in Predictive Modeling for Post‑Ablation Atrial Fibrillation
Congratulations to co-first authors Dr. Savannah Bifluco and Matthew Magoon, as well as Pat and co-senior author Dr. Nazem Akoum, on their new paper “Predicting arrhythmia recurrence post-ablation in atrial fibrillation using explainable machine learning”. Aiming to address clinical-ready technologies, this algorithm blends EHR and LGE-derived data to explain arrhythmia recurrence risk in ablation-treated patients via SHAP analysis. We are particularly proud to publish two major datasets alongside this paper, one containing 164 finite element meshes reconstructed from MRI scans…
New Article About Optogenetic Suppression in Cardiac Stem Cell Therapy
Kudos to CardSS Lab alumni Jamie S. Yang and Dr. Alexander R. Ochs, along with current members Dr. Chelsea E. Gibbs & Pat, who were the driving force behind the newly published article entitled “Computational Simulations Show Proof-of-Concept for Optogenetic Suppression of Ectopic Activity in Cardiac Stem Cell Therapy”. By investigating the efficacy of optogenetic modification, their simulations suggested WiChR-based optogenetic suppression of hPSC-CM graft-associated arrhythmia is feasible but must be carefully calibrated. More information can be found at Cardiovascular…
Recent Insights into Stem‑Cell‑Derived Cardiomyocyte Grafts and Arrhythmogenesis
CardSS Lab members Dr. Chelsea E. Gibbs and Pat recently published the study entitled “Population-based computational simulations elucidate mechanisms of focal arrhythmia following stem cell injection”. Key highlights of the paper include that individual stem-cell derived cardiomyocyte grafts can be arrhythmogenic and tend to be in areas with high host isolation. The full manuscript is available at The Journal of Molecular and Cellular Cardiology and ScienceDirect.
New review article on digital twins in cardiac EP
Pat has published a new review article with several distinguished European collaborators entitled “From bits to bedside: entering the age of digital twins in cardiac electrophysiology”. The full article is available open source via this link.
