Περίληψη:
This paper is based on the observation that all the available but also
forthcoming valves for transcatheter aortic valve implantation (TAVI),
do not examine how well the prosthetic valve will match the native
anatomy (3d structure) after implantation. 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.
