Course detail
Biomechanics III - Cardiovascular
FSI-RBM Acad. year: 2024/2025 Winter semester
The course starts with basic medical information on structure of cardiovascular system. It deals with loads and mechanical properties of its organs and tissues, including blood and its rheological properties. Properties of tissues are analysed in relation to their structure, from layers and fibres to the level of individual cells, their structure and mechanical behaviour. The course further presents most frequent pathologies of cardio-vascular system, especially atherosclerosis and its dependence on mechanical factors. All the gained knowledge is applied in computational models of isolated cell, artery and heart chamber, created in ANSYS software, not only in stress-strain analyses but also in fluid-structure interactions between a tissue and a liquid (blood).
Further, the course deals with technical fundamentals of therapeutic treatments and man-made replacements used at cardio-vascular system (vascular grafts, arterial stents, artificial heart valves, artificial heart pumps). The course deals with their technical principles, materials, production technology and basic requirements of biocompatibility.
