Abstract

Aortic valve disease is one of the most common heart valve diseases. Among various approaches treating this valve pathology we address aortic valve reconstruction with glutaraldehyde-treated autologous pericardium. This procedure is attractive due to its cost and effectiveness. A surgical planning system based on patient-specific modeling allows surgeons to compare different shapes of valve leaflet and to choose optimal reconstruction strategies. We develop a numerical framework for assessment of valve function that can be utilized by surgeons during patient-specific decision making. The framework includes automatic CT image segmentation, mesh generation, simulation of valve leaflet deformation by mass-spring approach. The final decision is based on uncertainty analysis and leaflets shape optimization. This paper gives a proof of concept of our methodology: segmentation, meshing and deformation simulation methods are presented in details.
