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.

用于成人三尖瓣修复的人工新腱膜:综述。
膨体聚四氟乙烯(ePTFE)新腱膜主要用于二尖瓣修复术(MVr),而在三尖瓣手术中的使用频率还没有得到很好的评估。我们对现有文献进行了回顾,以核实在各种三尖瓣病变中使用人工新腱索的发生率、适应症、技术和结果。我们发现共有 57 篇文章报道了在三尖瓣修复术(TVr)患者中使用 ePTFE 缝合线的情况。从这些文章中,我们可以获得有关基本疾病、手术技术和结果的充分信息,其中有 45 例患者使用新腱索的适应症是创伤后三尖瓣反流(n = 24)、感染性心内膜炎(8 例)、先天性瓣膜病(6 例)、心脏肿瘤切除术中的瓣膜损伤(3 例)或心脏移植术后反复心内膜活检后的瓣膜损伤(3 例)以及三尖瓣脱垂(1 例)。植入技术与目前使用人工新腱索进行中风瓣膜置换术的技术基本相同。在随访对照中,大多数病例的修复效果稳定,无住院死亡报告。迄今为止,使用 ePTFE 新腱索进行 TVr 的患者人数有限。尽管如此,它似乎是一种可行且可重复的技术,可作为 TVr 的常规手术手段。
