摘要：

An experimental study was designed to determine the damage of polytetrafluoroethylene (PTFE) sutures by DeBakey-type forceps and to measure tensile breaking strength of the damaged sutures. PTFE sutures were observed by scanning electron microscope before and after damage by holding and pulling with DeBakey-type forceps. Tensile breaking strength of the damaged PTFE sutures were measured. It was observed that the PTFE sutures may be damaged accidentally with DeBakey-type forceps in mitral valve repair.
