For different reasons, the myocardial tissue can produce a disorder in the electrical conduction of the heart, thus causing a cardiac arrhythmia. When the arrhythmia is life-threatening, cardiologists need to ablate bthe area responsible for the pathology ased on radio-frequency (RF).

This simulator has been developed at the end of my Ph.D. It includes two main steps: a catheter navigation in the cardiovascular system, and a second step of electrophysiology mapping. Using an hybrid (CPU-GPU) multihreaded architecture, this training system ensures a high level of interactivity and realism.

Based on GPU computing, our algorithm allows to compute the effect of cryoablation in the living tissues.

This visualization is done for simulating endovascular navigation.

This is the result of a simulation coupling the electrophysiology-mechanical simulation.
