The pulmonary valve (PV) is located between the right ventricle and the main pulmonary artery (PA), regulating blood flow from the heart into pulmonary circulation. Congenital heart diseases often cause an impairment of PV functionality, thereby requiring the replacement of the native valve with a prosthesis. Over the last years, percutaneous pulmonary valves (PPVs) have emerged as promising PV substitutes. The computational investigation of PV and PA hemodynamics enables the examination of blood flow patterns, allowing for biomechanical evaluations. Specifically, fluid-structure interaction (FSI) simulation allows for investigating the interaction between blood flow and biological structures such as PV leaflets and PA wall.
