Abstract:

BACKGROUND: Microwave ablation is a new technology for the surgical treatment of atrial fibrillation.
And we lack experience in the clinical application of microwave ablation both at home and abroad.
OBJECTIVE: To summarize the situation and progression about the study on thermal field of microwave ablation therapy for atrial fibrillation at home and abroad.
METHODS: The databases of CNKI, EI and SCI were selected to search the related articles about the thermal field of microwave ablation. The keywords were “ablation, atrial fibrillation, microwave, thermal field” in Chinese and English.
RESULTS AND CONCLUSION: Microwave catheter ablations make refined mapping of targeted spots which induce arrhythmia, cause coagulative necrosis to targeted spots and the adjacent cardiac tissue, and make damage to tachycardia lesions and pathway to eliminate arrhythmia. Computer simulation of thermal field can comprehensively reflect the thermal distribution and help medical workers to get an intuitive understanding of the therapeutic process before ablation surgery and put forward a detailed surgical plan. Simulation results, heating time and intensity can be modified during surgical operation according to certain parameters to achieve desired treatment results.
