Figure 2: (a) shows a reconstructed image from a scan performed in the mitral model. The alloy frame of the valve stent produces, probably due to its continuous motion, important scattering around the prosthesis. (b) illustrates how this scattering can be filtered, but through this process potential areas of mineralization within the cusps are also deleted. (c) shows the Faxitron X-ray image after explantation at 20 weeks, illustrating that there is clear calcification within two of the commissural areas.
