If the valve is not properly fitted in the native 3d anatomy, this may result in serious complications, which will affect short and long-term outcome. The latter are realized after valve implantation, they are difficult to correct and may significantly increase the cost of the procedure. Experienced operators take into account these factors when performing TAVI, as much as these can be appreciated by fluoroscopy and Computerized Tomography (CT) data; but they do not have available imaging algorithms that can guide them to the selection of the best valve for the specific anatomy or to quantify potential deformations of the valve during or after the procedure. Therefore, it is necessary to have a quantitative guidance that will assist interventional cardiologists on the selection of a certain valve, based on 3d structure, as well as on the evaluation of valve position and potential deformation. More specifically, a 3d reconstruction of an In-Vivo Bioprosthetic Aortic Valve (BAV) based on CT images is performed and the distances of the points on the wall of the Artificial Valve from the centerline are calculated.
