Computational models of cardiac electrophysiology are being investigated for improved patient selection and planning of therapies like cardiac resynchronization therapy (CRT). However, their clinical applicability is limited unless their parameters are fitted to the physiology of an individual patient. In this paper, a method that estimates spatially-varying electrical diffusivities from routin...

In Electrophysiology catheter ablation is an established treatment for cardiac arrhythmias. Nevertheless, complicated ablation procedures such as Pulmonary vein isolation for atrial fibrillation treatment are difficult to learn. This can be improved by a better integration of the image modalities available today and in the future Electrophysiology lab. In this paper, we present a method to regi...

Electrophysiology study (EPS) and radiofrequency catheter ablation (RFCA) are widely used for the diagnosis and treatment of cardiac arrhythmias. EPS and RFCA are very complicated procedures, requiring extended periods of time and advanced technologies that vary according to the disease of the patients. Fluoroscopy is used during EPS and RFCA to guide the catheter through the vessels while view...

Ongoing developments in cardiac modelling have resulted, in particular, in the development of advanced and increasingly complex computational frameworks for simulating cardiac tissue electrophysiology. The goal of these simulations is often to represent the detailed physiology and pathologies of the heart using codes that exploit the computational potential of high-performance computing archite...
