case_images: (a) A preoperative computed axial tomography showed severe calcification of the porcine
  and the native aortic root and (b) operative findings showed a leaflet tear and
  calcification of the non-coronary cusp.

case_images: fig1-2050313X221112363
case_images: Computed tomography revealed severe calcification of the aortic root (Figure 1(a)). After the aortotomy, a leaflet tear was found on the non-coronary cusp (Figure 1(b)).
case_images: The pathological findings of leaflets showed degenerated tissues and a few aggregated
  histiocytes and deposition of calcification and cholesterin. Inflammatory and immune
  responses were implicated.
