Successful reoperation using homografts for tricuspid and pulmonary valve regurgitation after radical double outlet right ventricle correction

Currently, there is a growing number of repeat cardiac interventions in children who have previously undergone surgery for congenital heart defects. This has renewed interest in identifying reconstructive materials that are resistant to the host’s defense mechanisms. Among such materials, cryopreserved homografts in various modifi cations are of particular relevance. Numerous studies have reported on the use of these prostheses in diff erent anatomical positions; however, cases involving simultaneous implantation of multiple homografts in a single patient for correction of congenital heart defects remain rare. To our knowledge, there are no published reports describing the use of a mitral homograft as a tricuspid valve substitute in combination with prosthetic pulmonary valve replacement using an allograft conduit. This report presents the first successful case of double valve replacement in a pediatric patient who had previously undergone radical correction of a double outlet right ventricle.
