Management of persistent tricuspid endocarditis with transplantation of cryopreserved mitral homografts.

Abstract

Transplantation of the human mitral valve in the tricuspid position for intractable infective endocarditis has been successfully performed in three young patients who were addicted to drugs. The maximum follow-up is 20 months. The rationale and historical basis for using this approach in the surgical treatment of patients with right-sided infective endocarditis is discussed and the appropriate literature reviewed. Because the technical aspects have been previously reported, this article can be considered an argument to renew past interest in atrioventricular valve replacement with fully biologic tissue of human origin.
