On the Accuracy of Eikonal Approximations in Cardiac Electrophysiology in the Presence of Fibrosis
(Springer, 2023)
Fibrotic tissue is one of the main risk factors for cardiac arrhythmias. It is therefore a key component in computational studies. In this work, we compare the monodomain equation to two eikonal models for cardiac ...
Maximum likelihood estimation of cardiac fiber bundle orientation from arbitrarily spaced diffusion weighted images
(Elsevier, 2017)
We propose an estimation scheme for local fiber bundle direction in the left ventricle directly from gray values of arbitrarily spaced cardiac diffusion weighted images (DWI). The approach is based on a parametric and ...
Temporal measures in cardiac structure and function during the development of obesity induced by different types of western diet in a rat model
(2020-01-01)
Obesity is recognized worldwide as a complex metabolic disorder that has reached epidemic proportions and is often associated with a high incidence of cardiovascular diseases. To study this pathology and evaluate cardiac ...
Differences in applied electrical power between full thorax models and limited-domain models for RF cardiac ablation
(Informa Healthcare, 2020-06-18)
Purpose: Most modeling studies on radiofrequency cardiac ablation (RFCA) are based on limited-domain models, which means the computational domain is restricted to a few centimeters of myocardium and blood around the active ...
Long-term high-fat diet-induced obesity decreases the cardiac leptin receptor without apparent lipotoxicity
(Pergamon-Elsevier B.V. Ltd, 2011-06-06)
Aims: Leptin resistance has been associated with cardiac lipotoxicity; however, whether leptin resistance is a risk factor associated with cardiac lipotoxicity at different time points in diet-induced obesity is unclear. ...

How drugs modulate the performance of the human heart
(2022)
Many drugs interact with ion channels in the cells of our heart and trigger heart rhythm disorders with potentially fatal consequences. Computational modeling can provide mechanistic insight into the onset and propagation ...
