Numerical Analysis on the Effects of Saline Injection and Deformation for Radiofrequency Catheter Ablation

Radiofrequency catheter ablation is an interventional procedure used to treat arrhythmia. An electrode that could inject saline has been developed prevent steam pop on heart tissue during radiofrequency ablation. Thus, we investigated numerical model the effect of injection and tissue’s deformation. In this study, hyperelastic was implemented analyze deformation due catheter’s contact force. Besides, advection–diffusion equation mixture between blood. We multiphysics predicts thermal lesions based mixing blood flow. The lesion maximum temperature in considered were smaller than other models did not consider mixing. Therefore, observed affected by higher electrical conductivity flow at a lower human body. researched considering affects temperature.
