Images of the valve (a) immediately after implantation and (b) explantation after 21.9 weeks at the same scale and in the same orientation. The “L” and “H” refer to the lung and heart end of the valve, respectively. In both images, the clips are visible on the ablumenal surface of the native pulmonary artery. (c) Cross-section of the heart showing normal right ventricle thickness after 21.9 weeks. (d) An explanted valve cut open to show its lumenal surface and leaflets. Stars indicate the original position of the commissures. (e) End-on view of a leaflet.
