Abstract:
Objective To construct a simulation model for percutaneous intramuscular septal radiofrequency ablation,and to explore the effects of different excitation voltages and ablation time on ablation areas.Methods By using Mimics software the segmentation and three-dimensional surface reconstruction of the tissue in various regions of the heart were realized based on the preoperative CT data of some patients with obstructive hypertrophic cardiomyopathy,and the reconstructed tissue was transformed into three-dimensional solid models with SolidWorks software,then the models were combined with the electrode needle mechanism established in COMSOL Multiphysics simulation software to form a simulation model for percutaneous intramuscular septal radiofrequency ablation.Electromagnetic and thermal multiphysics field boundary conditions were set with the model developed,and the tissue temperature distribution and the effects of ablation time and excitation voltage on the ablation region were simulated and analyzed.Results Simulation analysis of percutaneous intramuscular septal radiofrequency ablation could be carried out with the model developed,and different excitation voltages and ablation time proved to have significant effects on the effective ablation region.Conclusion The model constructed for percutaneous intramuscular septal radiofrequency ablation lays a foundation for the following research of the effects of multiple factors on ablation outcomes,which is of significance for parameter optimization in actual clinical treatment.[Chinese Medical Equipment Journal,2024,45(4):45-50]
