This paper deals with the study of fluid structure interactions in stenosed arteries. Stenoses in arteries are usually induced by the formation of an atheromatous plaque. This is a major issue of public health. Diagnoses based on simple image analysis (measurement of stenosis severity) are currently insufficient for reducing the impact of the cardio-vascular diseases, which may provoke a decrease of life expectancy for the 25-45 generation in the near future. Improved diagnoses should be devised for avoiding this issue. Therefore, there is a real medical and economical interest in developing tools and systems for determining and understanding the mechanical response of plaques in the arteries
