Cardiovascular system diseases are the main cause of deaths in developed and developing countries. The main reasons are myocardial infarction, heart failure, stroke and valvular diseases. These are caused mainly by arteriosclerosis. The valvular diseases involve a significant burden for the health care system and their frequency is rising with the patient age. This work describes the tools and numerical models appropriate for modeling the blood flow through the synthetic aortic valve and demonstrates the preliminary model used by authors. The overset mesh technique was applied to capture synthetic valve movement implanted within the aortic root, the aorta arch and the main branches of cardiovascular system. As the analyzed geometry scope does not include the whole cardiovascular system, there are artificial boundaries present at the inlet and at the outlets. To capture the cardiac system influence on the pressure values at these boundaries, the lumped parameter model was implemented. |
