A three-dimensional model for microwave treatment of heart rhythm disorders

Abstract

Presents a three-dimensional transfinite element approach to determine the dissipated power density in the heart chambers during microwave ablation for the treatment of heart rhythm disorders. This approach allows for modeling the heart in its entirety without assuming any axial symmetry. Furthermore, it makes no simplifications, neither on the shape of the microwave antenna nor on its the modes of propagation. It also takes into account the frequency dependence of the dielectric properties of the tissues. Hence, it allows for an accurate and realistic modeling of microwave ablation.
