1例52岁男性患者采用聚四氟乙烯（PTFE）缝线置换腱索行二尖瓣重建术。术后21天，由于自然腱索断裂导致二尖瓣关闭不全，再次行二尖瓣置换术。 对心脏瓣膜组织进行了肉眼和显微镜检查。 显示成纤维细胞增生。 然而，没有检测到内皮细胞层。据我们所知，我们的病例是第一次报告的组织学变化后，人类心脏瓣膜组织植入聚四氟乙烯缝线。
A case of mitral valve reconstruction with replacement of the chordae tendineae by polytetrafluoroethylene (PTFE) sutures is described in a 52-year-old man. 21 days after operation mitral valve insufficiency due to rupture of a natural chorda led to reoperation with mitral valve replacement. The cardiac valve tissue was examined both macroscopically and microscopically. It showed a proliferation of fibroblasts. However, there was no endothelial cell layer detectable.To the best of our knowledge our case is the first report of the histological changes in human cardiac valvular tissue after implantation of PTFE sutures.
