[Invited Paper] Pressure Change Simulation along Blood Flow in the Left Ventricle and the Aorta

The aorta is the most critical blood vessel in our body, and the aortic valve between the left ventricle (LV) and the aorta controls blood flow from the heart to the whole body. If the valve malfunctions, blood does not flow correctly, and enough nutrition is not conveyed all over the body. There is so much research on the aortic valve and the blood flow from the LV to the aorta; however, most of the previous works dealt with simplified cylindrical models and the blood flow in the model. The little study simulated the pressure change in the aorta and the LV using a real model generated from medical data. This paper summarizes our previous works that describe the model generation method from CT data, blood flow and pressure change in the aorta and the LV, and the comparison between the simulation results and the medical data.
