Abstract
Transcatheter aortic valve replacement is a promising new technique to treat patients with severe aortic stenosis due to its minimally invasive approach. Unfortunately, higher levels of thrombosis from utilizing this device instead of a standard surgical aortic valve means further research is needed to understand the cause. In order to understand areas of flow stasis and accurately model local flow patterns, a coronary flow model was developed which produces more physiologically accurate flow conditions than aortic flow models without this feature. Two experiments were performed, with and without the coronary, and hemodynamic and particle image velocimetry (PIV) data were collected. The results showed differences in the magnitude and flow patterns between the two cases during systole. Relevant applications of this system include studying the effect of coronary flow on flow patterns within a transcatheter aortic valve in the context of valve thrombosis.
