Mitral homograft in tricuspid position: indications for implantation and surgical technique

Highlights The article presents the latest data on techniques of implantation mitral homograft in tricuspid position, and identifies groups patients who are best suited for this method. Moreover, describes evolution type replacement, highlights that many surgical techniques, although justified, require further study to show demonstrate their advantages. Abstract Despite general trend cardiac surgery towards valve-preserving interventions, valve replacements remain relevant, search perfect prosthetic continues. Many believe replacement using a can be method choice certain situations. analysis studies found PubMed database led authors following conclusions: most use technique with infective endocarditis (IE), other indications congenital heart disease (CHD) rheumatic disease. Patients IE have undergone good medium-term prospects, respond well medical treatment recurrent IE. position remains intact even after endocarditis. In regard, it is possible perform reconstructive intervention case dysfunction without need repeated replacement. Such interventions relevant growing whom annuloplasty at first stage undesirable. also cost-effective due high cost low availability homografts. possibility valve-in-valve important may not survive open surgery. To date, there enough long-term short-term however, assumed results will positive provided appropriate strict patient selection ensured. come conclusion optimal includes sewing graft`s papillary muscles into wall myocardium right ventricle (RV), fixating them outer surface RV, anatomical positioning (anterior leaflet faces IVS), an ring.
