Radiographs (a) and necropsy results (b) of the hearts with the self-expanding prosthesis 6-months postimplantation. Both anterior and lateral views of the heart show an intact self-expanding stent frame without any fractures. The bottom row shows inferior and superior views of the self-expanding prosthetic aortic prosthesis; note that the entire stent frame crowns are covered as well as the annulus of the prosthetic valve is covered by opaque white tissue without pannus formation extending into the valve bases. The anterior mitral leaflet is unremarkable. The superior view of the aortic prosthetic valve shows good coaptation of the free edges of the valve leaflets. VS-ventricular septum, AML-anterior mitral leaflet.
