Cryopreserved mitral homograft in the tricuspid position for infective endocarditis: a valve that can be repaired in the long-term (13 years).

Herein is reported the long-term repair of a cryopreserved mitral homograft in the tricuspid position. A 34-year-old HIV-infected patient underwent tricuspid valve replacement in 1991 with a cryopreserved mitral homograft because of infective endocarditis. Chronic tricuspid regurgitation secondary to repeated endocarditis led to reoperation 13 years later. Mitral valve repair was performed with a rigid ring as there was annular dilatation; the valve tissue was intact. One year later, transthoracic echocardiography showed no tricuspid regurgitation. The cryopreserved mitral homograft is a potentially repairable valve in the long-term.
