A unified framework for geometry-independent operator learning in cardiac electrophysiology simulations
Bei Zhou, Cesare Corrado, Shuang Qian +9
Learning neural operators on heterogeneous and irregular geometries remains a fundamental challenge, as existing approaches typically rely on structured discretisations or explicit…
Regional heterogeneity in left atrial stiffness impacts passive deformation in a cohort of patient-specific models
Tiffany MG Baptiste, Cristobal Rodero, Charles P Sillett +13
The deformation of the left atrium (LA), or its biomechanical function, is closely linked to the health of this cardiac chamber. In atrial fibrillation (AF), atrial biomechanics ar…
TorchCor: High-Performance Cardiac Electrophysiology Simulations with the Finite Element Method on GPUs
Bei Zhou, Maximilian Balmus, Cesare Corrado +3
Cardiac electrophysiology (CEP) simulations are increasingly used for understanding cardiac arrhythmias and guiding clinical decisions. However, these simulations typically require…
Rapid calibration of atrial electrophysiology models using Gaussian process emulators in the ensemble Kalman filter
Mariya Mamajiwala, Cesare Corrado, Chris Lanyon +3
Atrial fibrillation (AF) is a common cardiac arrhythmia characterised by disordered electrical activity in the atria. The standard treatment is catheter ablation, which is invasive…
Cardiac Digital Twins at Scale from MRI: Open Tools and Representative Models from ~55000 UK Biobank Participants
Devran Ugurlu, Shuang Qian, Elliot Fairweather +10
A cardiac digital twin is a virtual replica of a patient's heart for screening, diagnosis, prognosis, risk assessment, and treatment planning of cardiovascular diseases. This requi…
In Silico Trials for Sex-Specific patient Inclusion Criteria in Cardiac Resynchronization Therapy: Advancing Precision in Heart Failure Treatment
Shuang Qian, Devran Ugurlu, Elliot Fairweather +12
Cardiac resynchronization therapy (CRT) guidelines are based on clinical trials with limited female representation and inconsistent left bundle branch block (LBBB) definitions. Con…
Probabilistic Richardson Extrapolation
Chris. J. Oates, Toni Karvonen, Aretha L. Teckentrup +2
For over a century, extrapolation methods have provided a powerful tool to improve the convergence order of a numerical method. However, these tools are not well-suited to modern c…
Real-time whole-heart electromechanical simulations using Latent Neural Ordinary Differential Equations
Matteo Salvador, Marina Strocchi, Francesco Regazzoni +3
Cardiac digital twins provide a physics and physiology informed framework to deliver predictive and personalized medicine. However, high-fidelity multi-scale cardiac models remain…
Evaluation of an Open-Source Pipeline to Create Patient-Specific Left Atrial Models: A Reproducibility Study
Jose Alonso Solis-Lemus, Tiffany Baptiste, Rosie Barrows +13
We present an open-source software pipeline to create patient-specific left atrial (LA) models with fibre orientations and a fibrosis map, suitable for electrophysiology simulation…
Fiber Organization has Little Effect on Electrical Activation Patterns during Focal Arrhythmias in the Left Atrium
Jiyue He, Arkady M. Pertsov, Elizabeth M. Cherry +5
Over the past two decades there has been a steady trend towards the development of realistic models of cardiac conduction with increasing levels of detail. However, making models m…
Calibrating cardiac electrophysiology models using latent Gaussian processes on atrial manifolds
Sam Coveney, Caroline H Roney, Cesare Corrado +4
Models of electrical excitation and recovery in the heart have become increasingly detailed, but have yet to be used routinely in the clinical setting to guide personalized interve…
Global Sensitivity Analysis of Four Chamber Heart Hemodynamics Using Surrogate Models
Elias Karabelas, Stefano Longobardi, Jana Fuchsberger +7
Computational Fluid Dynamics (CFD) is used to assist in designing artificial valves and planning procedures, focusing on local flow features. However, assessing the impact on overa…
An automated near-real time computational method for induction and treatment of scar-related ventricular tachycardias
Fernando O. Campos, Aurel Neic, Caroline Mendonca Costa +8
Catheter ablation is currently the only curative treatment for scar-related ventricular tachycardias (VTs). However, not only are ablation procedures long, with relatively high ris…
On the Incorporation of Obstacles in a Fluid Flow Problem Using a Navier-Stokes-Brinkman Penalization Approach
Jana Fuchsberger, Elias Karabelas, Philipp Aigner +4
Simulating the interaction of fluids with immersed moving solids is playing an important role for gaining a better quantitative understanding of how fluid dynamics is altered by th…
Universal atrial coordinates applied to visualisation, registration and construction of patient specific meshes
Caroline H Roney, Ali Pashaei, Marianna Meo +6
Integrating spatial information about atrial physiology and anatomy in a single patient from multimodal datasets, as well as generalizing these data across patients, requires a com…
