ABSTRACT
Expanded polytetrafluoroethylene (ePTFE) neochordae are predominantly used for mitral valve repair (MVr), while the frequency of their employment in tricuspid valve surgery is not well assessed. We have performed a review of the available literature to verify incidence, indications, techniques, and outcomes of the use of artificial neochordae in a variety of tricuspid valve pathologies. We found a total of 57 articles reporting the use of ePTFE sutures in patients in whom tricuspid valve repair (TVr) was performed. From such articles, adequate information on the basic disease, surgical techniques, and outcomes could be obtained in 45 patients in whom the indication to the use of neochordae was posttraumatic tricuspid regurgitation (n = 24), infective endocarditis (n = 8), congenital valvular disease (n = 6), valve injury during cardiac neoplasm excision (n = 3) or following repeated endomyocardial biopsies after heart transplantation (n = 3), and tricuspid valve prolapse (n = 1). Implant techniques generally replicated those currently employed for MVr using artificial neochordae. There were no reported hospital deaths with stability of repair in most cases at follow-up controls. TVr using ePTFE neochordae has been reported so far in a limited number of patients. Nevertheless, it appears a feasible and reproducible technique to be added routinely to the surgical armamentarium during TVr.
