Morphology and morphogenesis of implanted valve-containing prostheses of the pulmonary trunk for surgical correction of complex congenital heart diseases.
Morphology and morphogenesis of implanted valve-containing pulmonary trunk prostheses have been experimentally examined. It has been shown that 30 months after the operation there is total encapsulation of the graft and formation of the pseudointima layered with regenerated endothelium. In a xenograft sutured into the graft lumen, ultrastructural destructive changes develop gradually, however, the obturative function of graft has been preserved. All these facts allow us to recommend this type of graft for clinical use.
