Abstract:

This paper presents three-dimensions finite element analysis of 2.45 GHz microwave ablation for plagued coronary artery treatment. Any narrowing or blockage of the coronary arteries reduces blood supply to the heart tissue, following by reducing an amount of delivered oxygen and nutrients. This phenomenon inhibits a normal function of the heart muscle. In this research, we propose an application of finite element method to analyze and simulate a microwave ablation process on the blockage or plagued coronary artery. The investigation emphasizes on a reduction of plague or fat size that fixed around a coronary wall when heating by microwave thermal ablation. The simulation results of 3D analysis show the characteristic of temperature distribution in the coronary artery and a destructive area of plaque. 10 Watts of emission power at temperature 95 °C is used as a preliminary value. The simulation found that 3.21 mm3 of plaque size can be destroyed with 10 s. These obtained results usefully guide us to develop and more investigate on a further system in the future.

I. Introduction

Coronary artery disease, which typically increase over decades, is the most common form of heart disease and is the leading cause of death worldwide. In Thailand, every 15 minutes, a victim die from this coronary artery disease and about 25,000–30,000 people die every year which 3 times of increasing in last 10 years [1]. A complete blockage can cause a heart attack (also known as a myocardial infarction or MI) when lack of oxygen-rich blood flow causes the heart muscle to die. This may occur as a result of plaque rupture and blood clot formation at some site of a narrowed artery. Treatment of coronary artery disease can be done in various ways such as medications, cardiac catheterization for balloon percutaneous transluminal coronary angioplasty (PTCA), the use of thermal ablation and coronary artery bypass. The mentioned treatment should not be performed in some patients. Therefore, there has been research on the thermal conductivity used in the treatment of coronary artery disease. The use of microwave balloon begin to be trusted and widely used [2]. Liu is designed antenna in helical type [3]. Rappaport is experiment in-vitro heart [4]. Rosen is experiments put the antenna in contact with the heart muscle of a dog [5].
